Answer 1

Hi friend

Your answer
--------------------

Odometer reading at start of trip = 2000 km

Odometer reading at end of trip = 2400 km

Total time taken = 8 hours

Distance covered = (2400 - 2000) km = 400 km

So,

Average Speed = Total distance covered / Total time taken

(a) In km/h

=> Average speed = 400/8 km/h = 50 km/h

(b) In m/s

=> Average speed = (400/8 × 5/18 ) m/s = 13.88 m/s (approximately)
