Question

A bus takes 20 minutes to cover of distance of 18 km Calculate it's speed in km/ h and m/s


Explanation properly​

Answer 1

Answer:

Distance covered = 18 km

Time taken = 20 min = 20/60 hrs = 1/3 hrs

Speed in km/ h => 18/(1/3) km/h

=> 18 × 3 = 54 km/h

Speed in m/s => speed in km/h × 5/18

=> 54 × 5 / 18 m/s

=> 3 × 5 = 15 m/s
