Answer 2

$\huge\underline{\red{Given.\:\:...}}$

Two trains, each 50m long are travelling in opposite direction with velocity 10 m/s and 15 m/s The time of crossing is:-

$\huge\underline{\red{Answer.\:\:...}}$

4s

$\huge\underline{\red{Explanation.\:\:...}}$

Total length to cross L = 50 + 50 = 100m

relative volicity (w.r.t other train)

v = 15 - (-10) = 25m/s

$therefore \: t \: = \frac{l}{v} = \frac{10}{25} = 45$
