There are 2 trains P and Q moving in same direction. They are of equal length and cross a stationary pole in 5 seconds and 6 seconds respectively. In how much time would they cross each other?

30 seconds 11 Seconds 60 seconds 45 Seconds |
60 seconds |
Speed = \(\frac{Distance }{ Time}\) Let the length of train be x Speed of train P = \(\frac{x }{5}\) Speed of train Q = \(\frac{x }{6}\) Now, according to the question: \(\frac{x }{5}\) - \(\frac{x }{6}\) = \(\frac{2x }{ Time}\) \(\frac{x }{30}\) = \(\frac{2x }{ Time}\) Time = 60 seconds |
