Best answer
Distance covered by car = 57336.0 km - 57321.0 km = 15.0 km Time taken between 08:30 AM to 08:50 AM = 20 minutes = 20/60 hour = 1/3 hour So, speed in km/min

speed = distance covered/ time taken = 15Km / 20min =0.75Km / min

speed in Km /h

speed = distance covered / time taken = 15Km / 1/3h = 15x3 Km /1h = 45Km / h
