To determine the time it takes for a car to cover a distance of 1.2 km at a speed of 15 m/s, we can use the formula:
Time = Distance / Speed
Converting 1.2 km to meters, we have:
1.2 km = 1.2 * 1000 m = 1200 m
Plugging the values into the formula:
Time = 1200 m / 15 m/s
Time = 80 seconds
Therefore, it will take the car 80 seconds to cover a distance of 1.2 km at a speed of 15 m/s.
