A passenger train running at 54 km/h passes through a tunnel 400 meters long in 40 seconds. Find the length of the train.
Correct Answer: Option C
Explanation:
Speed of train = 54 * (5/18) = 15 m/s. Total distance covered in 40 seconds = 15 * 40 = 600 meters. Length of train = Total distance - Tunnel length = 600 - 400 = 200 meters.
Speed of train = 54 * (5/18) = 15 m/s. Total distance covered in 40 seconds = 15 * 40 = 600 meters. Length of train = Total distance - Tunnel length = 600 - 400 = 200 meters.

A train running at 54 km/h passes an active signal pole in 12 seconds. Find the length of the train.
Correct Answer: Option B
Explanation:
Speed = 54 * (5/18) = 15 m/s. Length of train = Speed * Time = 15 * 12 = 180 meters.
Speed = 54 * (5/18) = 15 m/s. Length of train = Speed * Time = 15 * 12 = 180 meters.
