Question

Delhi Metro rain covers a distance of 42 kilometre in 80 minutes what is the average speed of a train in kilometre hour-¹ as well as in ms-¹​

Answer 1

Answer:

31.5 km/h

and

8.75m/s

Explanation:

Average speed = Total distance traveled / total time taken = 42 km / 80 min = 0.525 km / min.

0.525 km / min

one hour = 60 min

Hence, one min = 1÷/60 hour.

= 0.525 km / 1÷ 60 h

31.5 km/h.

0.525 km / min = 0.525 km/min * 1000 m/60 s = 8.75 m/s.
