Answer:
Initial reading of the odometer of the car=57321.0km
Final reading of the odometer of the car=57336.0km
Distance covered by the car=Final reading of the car-Initial reading of the odometer of car
=57336.0km-57321.0km
=15km
The given car starts at 8:30am and stop at 8:50am
Therefore,time taken by the car to cover the distance is =(8:50-8:30)am=20 min
Distance covered by the car =15 km
Time taken by the car=20 min
Speed=Distance covered by time taken =15 by 20
=0.75 km/min
Again 60 min=1hr
20 min=1by 60 *20
=1by 3 hr
Speed = Distance by time
=15 by 3
=45 km/hr
