Question

A train is moving on a straight track with a speed of 35 m/s and its length is 100 m it overtakes another train of 120 m moving at 25 m/s in the same
direction. The time taken by the first train to overtake the second train is
Options
19 s
220 s
22 s
35 s
​

Answer 1

Relative velocity of overtaking =40−30=10m/s

Total relative distance covered with this relative velocity during overtaking

=100+200=300m

So, time taken =

10

300

=30s
