Question

Q.44
Two trains each of length 50 m are approaching
each other on parallel rails. Their velocities are
10 m/sec and 15 m/sec. They will cross each
other in -
(1) 2 sec
(2) 4 sec
(3) 10 sec
(4) 6 sec​

Answer 1

Answer:

4 SECOND

AS 100/15+10=4

Answer 2

Answer:

Total lenth=50+50=100m

As they are approaching towards each other so the relative velocity will be=10+15=25m/sec

So time=100/25 sec=4sec

Option (2)4sec

Hope this help you...
