Question

initial reading is when we start the car and final reading is when we stop the car but if we start the car next day the reading which will appear is initial or final​

Answer 1

Initial odometer reading=2000km

Final odometer reading=2400km

Total distance= Final distance- Initial distance

=2400-200=400km

Total time=8h

Average speed =?

Formula to be used :

Average speed= Total Distance/Total time

Average speed in Km/hr:

Average speed=400/8

=50 km/hr

Average Speed in m/s:

1km/hr=5/18 m/s

∴50km/hr=50x5/18=250/18=13.88m/s
