Question

If A covers 2.5 km in 30 minutes and B covers 5 km in 45 minutes then who is travelling in higher speed​

Answer 1

Answer: B is travelling in higher speed

Explanation:

Distance covered by A = 2.5 km

Time taken by A = 30 mins = 1/2 hr

Hence, speed of A = distance /time

                                = 2.5 ÷ 1/2

                               = 2.5 x 2

                                = 5km/hr

Distance covered by B = 5km

Time taken by B = 45 mins = 3/4hr

Hence, speed of B = distance/time

                                = 5 ÷ 3/4

                                = 5 x 4/3

                                = 20/3 ≈ 6.67 km/hr

Since, 6.67 > 5 , speed of B is more than A

Answer 2

Total distance covered = 16 km

total time required = 15 min = 41 hr

We knw

Speed = TimeDistance

Speed = 1/416=64 km/h

Hence speed of train is 64 km/h
