Question

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.

• A. 20 km/h
• B. 30 km/h
• C. 40 km/h
• D. 50 km/h

Answer 1

The correct option is A

20 km/h

We use the formula, $Averagespeed=\frac{Totaldistance}{Totaltime}$

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 = $\frac{100}{5}=20\frac{km}{hr}$
