xample 8.2 The odometer of a car reads2000 km at the start of a trip and2400 km at the end of the trip. If thetrip took 8 h, calculate the averagespeed of the car in km h1 and m s

Answer» <p>Actual distance = 2,400-2,000km=400km</p><p>Time taken = 8 hours </p><p>Average speed = Total distance÷Total time = 400km÷8hours = 50km/h</p><p>400km = 4,00,000 m8 hours = 28,800seconds</p><p>Average speed = Total distance ÷ Total time =4,00,000m÷28800seconds= 13.89m/s</p><p> </p> <p>2000 +2400 = 4400 /2= 2200</p>
