Answer 2

Question :

A car covers a distance of 20 km in 20 minutes. Calculate its speed in km/h and m/s.

Answer :

The speed of the car in m/s is 16.67 m/s and in km/h is 60.01 km/h.

Given :

Distance covered = 20km

Time taken = 20mins

To find :

Speed of the car in km/h and m/s

Solution :

We know that speed is the distance travelled in one second

speed = distance/time

Distance = 20 km = 20000 m

Time taken = 20 minutes = 20×60 = 1200 seconds

Speed in m\s = 20000/1200 = 16.67 m/s

Hence, speed in km/h = 16.67 × 18/5 = 60.01 km/h

Therefore, The speed of the car in m/s is 16.67 m/s and in km/h is 60.01 km/h.
