Question

Two trains running in opposite directions cross a man standing on the platform in 27 seconds and 17 seconds respectively and they cross each other in 23 seconds. The ratio of their speeds is?

Answer 1

\[Speed_{1} = \frac{d_1}{t_1 } = \frac{d_1}{27}\]

Answer 2

\[Speed_2 = \frac{d_2}{t_2} = \frac{d_2}{17}\]

Answer 3

When trains will be running in opposite, their relative speed will add up:
So:
\(Speed = Sp_1 + Sp_2\)

Answer 4

ok
