A train covers a distance of 54 km from station A to station G in an hour via stations B, C, D, E and F. On each station, the train stops for 72 seconds. What is the speed of the train in km/h?

Correct option is D

Given:

Distacne = 54km

Time taken = 1 hour

Stoppage at each station = 72sec

Formula Used:

​$$Speed = \frac{Distance}{Time}$$​​

Solution:

If train leaves from A and reaches G then stoppages taken at B,C,D,E and F only

The total time taken at 5 station = $$72 \times 5$$​ = 360sec

Total time in minutes spend in stoppages =$$\frac{360}{60}$$​= 6 minutes

Total time the train was running = 60 -6 = 54 minutes

Times in hour =$$\frac{54}{60}$$​ =0.9hour

Speed of train =$$\frac{54}{0.9}$$​ = 60km/hr
