Two trains, each 30 ~m long are travelling in opposite directions with velocities 5 ~m / s and 10 ~m / s . They will cross after

Options

  1. A4 ~s
  2. B3 ~s
  3. C2 ~s
  4. D1 ~s

Correct answer

A. 4 ~s

Step-by-step solution

Relative velocity of one train w. r. t other =5+0=15 ~m / s Total length to cross ( L )=30+30=60 ~m t= L V = 60 15 =4 s
