Answer:
The initial reading of the odometer of the car =57321.0 km
The final reading of the odometer of the car = 57336.0 km
The car starts at 8:30 AM and stops at 8:50 AM.
Distance covered by car = (57336 - 57321) km = 15 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 travelled)/ (Time)
= (15km)/ (20min)
= 0.75km/min
Speed in km/h Speed = (Distance travelled)/ (Time)
= (15km)/ (1/3h)
= (15 x 3) km/ (1h)
= 45km/h
