a train is moving at speed of 25 kmph , another train
moving the same direction at a speed of 49 kmph crossed a
man in the first train in 10 sec ? wht is the length of the
second train ?
Answer Posted / reddipavanakrishna
Relative velocity of trains = 49kmph -25 kmph = 24kmph
=6.67m/s
Time taken to cross the first train = 10 sec
Length of the second train = Relative Velocity * Time taken
to cross the first Train = 6.67 *10 = 66.7 metres
