EXPLANATION.
- GIVEN
A train 180 m long is moving at 35 km/hr.
another train moving in the opposite direction
at 25 km/h along a parallel track passes by it in
18 seconds.
Find the length of the second train.
according to the question,
Let length of another train be = x
Distance = 180 + x
Speed = 35 + 25 = 60 km/hr
=> 60 X 5 / 18 = 50 / 3 m/s
Time = 18 seconds.
Distance = Speed X Time.
=> 180 + x = 50/3 X 18
=> 180 + x = 300
=> x = 120 m
Therefore,
The length of second train = 120 m
