Distance covered by the car in 1st hour = 60 km
Distance covered by the car in 2nd hour = 90 km
Distance covered by the car in 3rd hour = 150 km
Distance covered by the car in 4th hour = 120 km
Average speed = Total distance covered/Total time taken
= ( 60 + 90 + 150 + 120)/4
= 420/4
= 105 km/h
Distance covered by the car in 2nd hour = 90 km
Distance covered by the car in 3rd hour = 150 km
Distance covered by the car in 4th hour = 120 km
Average speed = Total distance covered/Total time taken
= ( 60 + 90 + 150 + 120)/4
= 420/4
= 105 km/h
