Question

A car takes 20 minutes to cover a distance of 24 km. Find its speed in m/s.

Answer 1

We know that speed is the distance travelled in one second
speed = distance/time
distance = 24 km = 24000 m
time = 20 minutes = 20*60 = 1200 seconds
speed = 24000/1200 = 20 m/s
the required speed to cover the distance is 20 m/s
