But have we ever thought about estimating distance, speed and time if we want to go somewhere? I'm sure it's easy for you to answer. I've known for a long time that when I go to the village I usually go in the afternoon or evening, until tomorrow morning before noon, just count the hours. That's true, but what if we've never visited the place we're traveling to? What do you know? Of course not, right? By knowing the distance or time or speed, we can estimate when to leave, slow or slow, far or near, and when to arrive.
Simply put, the formula for distance, time and speed is:
S = V x t
V = S/t
t = S/V
Wow, don't worry, it's actually that easy. Get rid of the phobic habit of seeing formulas that immediately blur your vision and disorient your thoughts. First, keep in mind that it is easy. Over time you will get used to it and it will become easier. Usually we are what we habituate in our minds.
S is Distance, usually like KM (Kilo Meters)
V is Speed, usually like KM/HOUR
t is Time, or the length of time that passes, aka duration, usually like Clock
in time there is usually a Start Time (t1) and an End Time (t2), so
t = t2 – t1
t1 = t2 – t
t2 = t1 + t
If you're still confused, just shorten it!
S = V X T
V = S/T
T = S/V
S = DISTANCE = KM
V = SPEED = KM/HOUR
T = TIME = HOURS
T = T2 – T1
T1 = T2 – T
T2 = T1 + T
T = TIME (HOURS)
T1 = INITIAL TIME
T2 = END TIME
So, what do you want to do with this formula? Is that fried!? Yes, no way! We calculate it like we would if we wanted to treat you (Azzeek…..Museek). So, how do you do it? It's easy. First, if we get information that the distance to a place is around 600 KM, is it far or near? For example, if you go at 7 in the morning, what time do you arrive? Wow... this is a crossword puzzle that must be solved...
It's easy, just enter the formula. For example, we assume we ride a motorbike, usually a motorbike:
f the speed is 60 km/hour,
if it's 50 km/hour,
if slow, 40 km/hour.
For example, let's just calculate the speed of a motorbike, namely,
SPEED 60 km/h.
This means that V is 60 km/hour (V = 60 k/hour).
I already knew the DISTANCE, namely 600 km/hour.
DISTANCE = 600 km/hour
This means that there is only one more formula that has not been found, namely:
TIME =?
How long on the road so you know what time it will arrive.
That was the formula:
S = V x t
(if looking for DISTANCE)
t = S/V or DISTANCE BY SPEED means
t = 600/60 = 10 HOURS
If you left at 7 in the morning, that means you'll arrive at:
07.00 AM + 10 HOURS = AT 05.00 PM.
This means it can still be reached during the day, or not until late at night, meaning you won't have to stay overnight on the road because you're on a motorbike. It's easy, right... But, if you don't have traffic jams on the road and don't use a lot of time, stop at stalls for a long time or fall asleep while taking a break at the gas station. If not, it's possible that it will arrive at dusk or evening.
What if you use a car?
Just count. Cars usually have a speed of 80 km/h, so
TIME = DISTANCE DIVIDED SPEED
T = 600/80
T = 5 HOURS.
That means it's coming:
T2 = T1 + T
T2 = JAM 07.00 AM + 7,5 HOURS
T2 = 02.30 PM
If on the road there are no obstacles to slow it down, like when we ride a motorbike in the explanation above.
What if we heard about a place that people who have been there say that when they go in the morning they usually arrive at 10 at night, which means it's already dark. We just have to count. If the trip leaves at 07.00 WIB until 10 pm or 22.00 WIB, it means the TIME is around 15 HOURS (22 – 7 = 15), meaning if you ride a motorbike with an average SPEED generally 60 km/hour, it means the DISTANCE is around :
S = V x t
S = 60
x 15
S = 900
KM.
If you travel by car which usually has a SPEED of 80 km/hour, it means it could take an hour to arrive;
t = S/V
t = 900/80
t = 11,25 HOURS
t2 = t1 + t
t2 = 07.00 AM + 11,25 HOURS
t2 = 06.15 PM
Which means it's better to go by car, in the sense that at least you won't be late at night.
There's another thing like this, we know that when we usually go to a place, for example going home, or going home, usually if we go at 7 in the morning we arrive at 1 in the afternoon, and even then it's already fast. Due to temporary unfit conditions, for example having a toothache, it's possible that you won't be able to go fast, at most it will be moderate, aka it will be slow, what do you think, what time will it arrive? If so, let's calculate again. Previously, when it was fast, it usually left at 7 and arrived at 1 in the afternoon. It is estimated that you are riding a motorbike, meaning the possible speed is 60 km/hour and the time on the road is 6 hours. This means that the estimated distance is:
S = V x t
S = 60
x 6
S = 360
km.
So, if the speed is not too high, aka slow (approximately 40 km/hour), it means that the clock has arrived.
t = S/V
t =
360/40
t = 9 hours.
t2 = t1 + t
t2 = 07.00 am+ 9 hours
t2 = 04.00 pm
he came. Even then, it's already slow. You can even rest for around 2 hours, it feels like you've been resting for a total of 2 hours, if you don't lie down.
So it's actually very easy to calculate distance, time and speed. Especially in mathematics where numbers are certain to be known without using estimates. For example:
Question 1:
Andi drove from city A to city B at a speed of 70 km/hour. Meanwhile the journey time is 5 hours. What is the distance between city A and city B?
Known: V = 70 km/h, t = 5 hours
Asked: S =?
Answered:
S = V x t
S = 70 x 5
S = 350 km
So, the distance from city A to city B is 350 KM
Question 2:
The distance between city A and city B is 500 km. Andi drove to that place at an average speed of 50 km/hour. How long did Andi take while on the road?
Known: S = 500 km, V = 50 km/h
Asked: t =?
Answered:
S = V x t
t = S/V
t = 500/50
t = 10 hours
So, Andi's travel time is 10 HOURS
Question3:
The distance from city A to city B is 400 km. The time Andi traveled was 4 hours. What is the average speed?
Known: S = 400 km, t = 4 hours
Asked: V =?
Answered:
S = V x t
V = S/t
V = 400/4
V = 100 km/h
So, Andi's average speed is 100 KM/H
Question 4:
Andi goes to city A at a speed of 60 km/hour. He left home at 6 am. If he reaches city A at 6 p.m., what is the distance to city A?
Known: V = 60 km/hour, t = 6 pm – 6 am = 17.00 – 06.00 = 12 hours
Asked: S =?
Answered:
S = V x t
S = 60 x 12
S = 720 km
So the distance to city A is 720 KM
Question 5:
The distance from city A to city B is 500 km. Andi left home at 6 am and arrived at 11 am. What is the average speed?
Known: S = 500 km, t = 11 am – 6 am = 5 hours
Asked: V =?
Answered:
S = V x t
V = S/t
V = 500/5
V = 100 km/h
So, the average speed is 100 KM/H
Question 6:
If the distance from city A to city B is 400 km and the average speed is 100 km/hour, what time will Andi arrive if he leaves at 6 am?
Known: S = 400 km, V = 100 km/hour, t1 = 06.00 WIB
Asked: t2 =?
Answered:
S = V x t
t = S/V
t = 400/100
t = 4 hours
t = t2 – t1
t2 = t1 + t
t2 = 06.00 + 4 hours
t2 = 10.00 WIB
So, Andi arrived at city A at 10.00 WIB or 10 AM
Question 7:
If the distance between city A and city B is 77 km and the average speed is 77 km/hour, what time will Andi leave if he arrives in city B at 7 maghrib?
Known: S = 77 km, V = 77 km/hour, t2 = 7 maghrib or 19.00 WIB
Asked: t1 =?
Answered:
S = V x t
t = S/V
t = 77/77
t = 1 hour
t = t2 – t1
t1 = t2 – t
t1 = 19.00 – 1 hour
t1 = 18.00 WIB
So, Andi departed from city A at 18.00 WIB or 6 PM
How? It's easy, right? Of course not! So how? Yes, over and over again. What if you don't want to? Yes, just take a pillow and go straight to sleep. What if you don't want to? Which cell phone is your cell phone, give it to him! That's it! Yes, never mind if that's the case, but while reading again, read again so you can be good at math, aka arithmetic, key...
Hopefully this article is useful and brings blessings while on the road. But don't forget, before leaving, read the prayer first, okay, and don't forget to follow all the rules and regulations in traffic, key, thank you, wassalam.
