Question

the odometer of a car rates 2000 km at the start of a trip and 2400 km at the end of a trip if the trip took 8 hours calculate the average speed of of the car in kilometre per hour and metre per second please give me this questions of physics

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

Answer 2

total distance = 2400km
total time = 8 hrs
average sped= distace /time
= 2400/8 = 300km/h
....
300×1000/3600=83.33m/s
