Odometer initial reading : 57321 km
Odometer final reading :57336 km
Distance covered : 57336-57321 km
= 15 km
Time taken : 8:50-8:30
= 20 min
Formula :
Speed = Distance/Time
= 15/20
= 3/4 km/min
in km/hr→
= 3/4 * 60
= 45 km/hr

initial reading equal to 57321 0.0
final reading = 273 6.0 km
initial time 8:30 a.m.
final time 8:50 a.m.
Total distance covered by car equal to 5 7 3 2 1 - 5 7 3 3 6 =15
total time equal to 8: 30 - 8:50 equals to 20 minutes
speed equal to distance upon time so 15/20=0.75km/m
speed in km/hr =0.75*60=45 km/h
