B Correct answer
Explanation

Speed = Distance / Time = 360 / 36 = 10 m/s. Total distance to cross platform = 360 + 600 = 960 m. Time = 960 / 10 = 96 seconds.

AI explanation

First, find the speed of the train by dividing its length by the time it takes to cross the pole: 360 m divided by 36 s equals 10 m/s. When crossing a platform, the total distance the train must cover is its own length plus the platform's length, which is 360 m plus 600 m, totaling 960 m. We then use the formula time equals distance divided by speed to find the required time. Dividing 960 m by the speed of 10 m/s gives a time of 96 seconds. The train will take 96 seconds to cross the platform.
