Solution

## The correct option is A 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
