Question

two trains of equal length are running on parallel lines at the same directuon at the speed of 44kmph and 38kmph if the faster train crosses the slower one in 0.8 minutes what is the length​

Answer 1

Answer:

since both the trains are traveling in the same direction. Therefore by relative speed,

overall speed=44-38=6kmph=5/3 ms^-1

total distance=

2d since we have to add the length of both trains.

total time=0.8×60s=8×6s

We know that

Distance= Speed×Time

2d=(5/3)(8)(6)

d=(5)(8)(2)/2

d=40m
