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, what is the average speed of the vehicle?
The correct option is D 20 kmph
Odometer reading, before the trip =22256 km
Odometer reading, after the trip =22356 km
So the distance travelled in the trip=22356−22256=100 km
Time taken for the trip =5 hr
Average speed = Total distance travelledTotal time taken
∴ Average speed =1005=20 kmph
