The odometer of a vehicle has an initial reading of 22256 km. After the trip, it shows a reading of 22356 km. If the time taken for the trip is 5 hours, find the average speed of the vehicle.
20 km/h
We use the formula, Averagespeed=TotaldistanceTotaltime
Total distance travelled is equal to the difference between the final and the initial readings of the odometer.
That is, (22356 - 22256) km = 100 km
Total time taken is 5 hours
Therefore, average speed = 1005=20kmhr
