Question

Two trains of length 200m
&180m respletively are
running in opposite directions
on parallel tracks. If their
speeds be 30km/hr &24km/hr respectively, then the
time taken by them to cross
each other is-​

Answer 1

Answer:

if we consider 200m train at rest then its relative speed will be 30+ 24 = 54

total distance it have to cover to cross the train is (200+180) 380

time taken is distance/speed

time = 380/54
