Answer:
Two trains of equal length are running on parallel lines in the same direction at 46 km/hr and 36 km/hr. The faster train passes the slower train in 36 seconds. The length of each train is ?
40 meter
45 meter
50 meter
55 meter
Answer: Option C
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
