Question

The odometer of a car reads 2000 km at the start of a trip and 2400 km at the end of
the trip. If the trip took 8 h, calculate the average speed of the car in km/h and m/s.

Answer 1

Odometer reading at the start of the trip=2000km
Odometer reading at the end of the trip=2400km
Actual distance covered by the car=2400-2000km=400km
Time=8hrs
Average speed=total distance /Total time
400/8=20km/h
Speed of car in m/s =5/18*20=5.555555..... keep it as 5.5
Hope that it helps
