Solution: Distance. = 2400 Time elapsed, 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–1 and m s–1. covered by the car, km – 2000 km = 400 km t = 8 h. Average speed of the car is, s 400 km.
