A train has a speed of 15m/s and another train having speed of 25m/s. One train crosses a platform in 25seconds and other train crosses the same platform in 38seconds. If train A passes a pole in 25seconds,find the length of train B.
Answers
Answer:
Given:
Speed of the train = 15 m/s.
Length of the platform = 300 meters
Time taken by train to cross the platform = 35 seconds.
Concept used:
When the train crosss the platform, then
the total distance traveled by the train will be equal to the sum of length of the train and the length of the platform.
Formula used:
Distance = Speed × Time
Calculation:
Let the length of the train be x.
According to the question,
300 + x = 15 × 35
⇒ 300 + x = 525
⇒ x = 525 - 300
⇒ x = 225
∴ The length of the train is 225m

Given,
Speed of the train=15m/s
Speed of the another train=25m/s
Time to cross to platform=25s
Another train crosses the platform=38s
To Find,
Length of train B.
Solution,
Here, speed of the train = 15 m/s.
Length of the platform = 300 meters
Time taken by train to cross the platform = 35 seconds.
When the train crosss the platform, then
the total distance traveled by the train will be equal to the sum of length of the train and the length of the platform.
We know,
Distance = Speed × Time
Let the length of the train B is x.
According to the question,
300 + x = 15 × 35
⇒ 300 + x = 525
⇒ x = 525 - 300
⇒ x = 225
Hence,the length of the train B is 225m.
