Initial reading of the odometer of the car = 67859.0 km
Final reading of the odometer of the car = 67862.0 km
Distance covered by the car = Final reading of the odometer of the car - Initial reading of the odometer of the car
= 67862.0 -67859.0 = 3km
The given car starts at 9:00a.m. and stops at 9:30a.m.
Therefore, time taken by the car to cover the distance is (9:30— 9:00) min = 30 min
Distance covered by the car =3 km
Time taken by the car = 30 min
Speed = distance covered/time taken
Speed= 3/30= 0.1 km/min
60min= 1h
30 min= 1/60×30= 1/2 h
Time taken by the car = 1/2h
Speed = distance covered/time taken
Speed = 3/1/2= 3×2= 6 km/hr
