Question

The average speed of a train in the onward
journey is 25% more than that in the return
journey. The train halts for one hour on
reaching the destination. The total time taken
for the complete to and for journey is 17 hours,
covering a distance of 800 km. The speed of
the train in the onward journey is:
(a) 50 km/hr (b) 53 km/hr
(c) 52 km/hr (d) 56.25 km/hr

Answer 1

Answer:

Step-by-step explanation:

Let it's velocity in the return journey be v, then its onward velocity will be 5v/4.  

400/v + 400/(5v/4) = 16  

25/v + 20/v = 1  

v = 45 km/hr.
