Question

A car gave a reading of distance 2000km at the start of the trip and 2288km at tge end of the trip . if the trip took 8 hours calculate the average speed of tge car in m/s

with step and class 9 CBSE​

Answer 1

Answer:

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.

Answer 2

Answer:

13.9 m/s

Explanation:

50 km/h or 13.9 m/s

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.
