If an X-m long train running at a speed of 63 m/s crosses a railway platform in 28 sec, find the value of X, if the length of the railway platform is 213 m.

Correct option is B

Given:
Speed of the train = 63 m/s
Time taken to cross the platform = 28 sec
Length of the platform = 213 m
Formula Used:
Total Distance = Speed × Time
Total Distance = Length of Train + Length of Platform
Solution:
Let the length of the train be X.
Total distance covered = X + 213
According to the formula:
X + 213 = 63 × 28
X + 213 = 1764
X = 1764 - 213
X = 1551
The length of the train is 1551 m.
Final Answer
So the correct answer is (b)
