Answer:
Correct option is
A
50 km/h or 13.9 m/s
Answer is A.
It is given that the total distance travelled by the car is 2400 km-2000 km = 400 km, that is, 400000 m and the total time taken =8 hours, that is, 8×60×60=28800seconds..
Average speed in km/hr = total distance/total time = 400/8 = 50 km/hr.
Average speed in m/s = total distance/total time = 400000/28800 = 13.89 m/s.
