Question

The odometer of a car reads 2000 km at the start of a trip and 2288 km at the end of the trip . if the trip take 8 hours ,calculate the average speed of the car​

Answer 1

Explanation:

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

this is the correct answer
