The odometer of a car reads 2000km at the start of a trip and 2400 km at the end of the trip. If the trip took8h, calculate the average speed of the car in km h-1 and ms-1
Total distance = 2400km-2000km = 400km = 400000m
Total time= 8hrs =28800 sec
Average speed in km/h = total distance/ total time = 400/8 = 50km/h
Average speed in m/s=Total distance/total time= 400000/28800 = 13.89 m/s
