Question

the speed of train is 50km per hou . what distance will the train travel in 4 hour . in the method of three.​

Answer 1

Answer:

Suppose the train travels for one hour on the outward journey. So it covers 30 km.

On the return journey it travels at 50 kmph so it takes 30*60/50 = 36 min or 0.6 hours.

Average speed = Total distance covered, both ways/ Total time taken, both ways.

= (30+30)/(1+0.6)

= 60/1.6

= 37.5 kmph
