Question

5. A person takes observations from odometer
of his own motorcar while starting journey as
well as after 40 min of his journey, which are
found as 1046 km and 1096 km respectively.
What would be the average speed of the
motorcar ?​

Answer 1

Final distance= 1096km

Initial distance= 1048km

Time taken= 40min = 40/60 h

Average speed

= Total Distance covered/ Total time taken

= Final distance - initial distance/ total time taken

= 1096-1048/(40/60)

= 48/(40/60)

= 48*60/40

= 72km/h

No the speedometer may or may not show this reading, because the vehicle can move at different speeds while transition and doesn't have a constant speed. But this is the average speed.
