Question

The odometer of a car reads 2400 km at the start of a trip and 2800 km at the end of the trip. If the trip took 8 h, calculate the average speed of the car in km/h and m/s.​

Answer 1

Answer:

50km/h , 13.88m/s

Explanation:

At the start = 2400km

at the end = 2800km

So, total dist. covered = 2800km - 2400km

= 400 km

= 400000m

time taken = 8 h

= 28800s

Speed in km/h = d/t

= 400km / 8h

= 50km/h

Speed in m/s = d/t

= 400000m /28800s

= 13.88m/s
