Question

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 km h-1 and ms-1
​

Answer 1

average speed = total distance by total time

so, average speed = 400/8km/kmph

=50km/h

Answer 2

Total distance travelled by car = 400km ,

time taken = 8 hours

speed = ?

we know,

speed = distance/time

=> 400/8
=> 50km/h

In m/s

=> 50 ×5/18
=>. 13.888 m/s


therefore speed , in km/h => 50km/h
and. in m/s. => 13.888m/s

hope it will be helpful...
