The car, moving evenly, overcomes 80 km in an hour. how much will the car cover in 120min? in 30 minutes? in 15min?

In order to solve this problem, you will need some knowledge about uniform motion.
To begin with, let’s translate 120 minutes, 30 minutes and 15 minutes into hours. There are 60 minutes in one hour, which means:
120 minutes = 2 hours;
30 minutes = 1/2 hour;
15 minutes = 1/4 hour;
In order to find out how much a car will travel in a certain period of time, we use the formula:
S = Vt;
V is the speed;
t is time;
1) S = 80 * 2 = 160 km;
2) S = 80 * 1/2 = 40 km;
3) S = 80 * 1/4 = 20 km;
Answer: 120 km, 40 km, 20 km.
