Question

odometer of a car reads 1800 km at the start of a trip and 2400 km at the end of the trip if the trip took 10 hours calculate the average speed of the car in kilometre per hour and metre per second

Answer 1

Answer:

Average speed = 60 Km/hr. Or 16. 66 m/s.

Explanation:

Initial speed =d1=1800 km

Final speed =d2 = 2400 km

Time = t = 10 hr

Average speed, S = d2-d1/t

S = 2400 - 1800 / 10

S = 600/10

S = 60 Km/hr

In m/s

S = 60 ×1000/3600

S = 16. 6666 m/s
