Question

Calculate the speed of car in metre per second if it covers a distance of 360 km in 6 hours

Answer 1

Speed =Distance/Time
Speed=360/60
Speed= 60km/h
60km/h =16.6666667m/s

Answer 2

1km =1000m
so, 360km=360×1000=360000
1hour =60min
1min= 60sec
1hour=60×60=3600
6hour=6×3600=21600
so there fore =360000/21600
=16.6m/s
