A train tracking at 90 km/h clears a static warehouse tunnel in 20 seconds. If the train length is 150 meters, find the tunnel length. MCQ with Answer and Explanation

Explanation:
Since time is inversely proportional to speed when distance is constant, the ratio of time taken is the reciprocal of the speed ratio: 1/3 : 1/5 = 5 : 3.

Explanation:
Speed of train = 180 / 12 = 15 m/s. Converting to km/h = 15 * (18/5) = 54 km/h.

Explanation:
Speed = 200 / 22 m/s = 100 / 11 m/s. In km/h = (100 / 11) * (18/5) = 360 / 11 = 32.72 km/h.
