Question

X
speed of light, that is,
ms!
8.
Example 8.2 The odometer of a car reads
2000 km at the start of a trip and
2400 km at the end of the trip. If the
trip took 8 h, calculate the average
speed of the car in kmh and ms.

Answer with steps​

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.
