Question

A car is moving at a speed of 15 ms-1. In how much time will it cover a distance of 1.2 km?


​

Answer 1

Answer:

As we know that

Speed= distance/time

Or time = distance/speed

According to your question

Speed=15m/s

and. Distance=1.2km. ,we must change kilometer in meter because given speed is in m/s

D= 1.2km = 1.2×1000m =1200meter

Time = distance/ speed

1200/15 =80second

Or. 1min and 20 sec will be your answer.
