Question

Two trains of equal length are running on parallel lines in the same direction
at 32 km/hr and 50 km/hr. The faster train passes the slower train in 40
seconds. The length of each train is?

Answer 1

Step-by-step explanation:

Let the length of each train is x meter

Distance will be x+x = 2x

Relative Speed = 46-36 = 10 km/hr

= 10*(5/18) = 25/9 m/sec

Distance = Speed*Time

\begin{aligned}

2x = \frac{25}{9}*36 \\

2x = 100 \\

=> x = 50

\end{aligned}

So length of both the trains are 50 meters
