How much time will a 270 metre long train running at a speed of 360 me...
To solve this problem, we need to determine the time it takes for the train to completely cross the platform.
Given:
Length of the train = 270 meters
Speed of the train = 360 meters/second
Length of the platform = 270 meters
Step 1: Calculate the time taken by the train to cross its own length
The time taken by the train to cross its own length is given by the formula:
Time = Distance/Speed
Time = 270 meters / 360 meters/second
Time = 0.75 seconds
Step 2: Calculate the time taken by the train to cross the platform
Since the length of the platform is the same as the length of the train, the train needs to cover double the distance to completely cross the platform. Therefore, the distance to be covered is 2 * 270 meters = 540 meters.
Using the formula:
Time = Distance/Speed
Time = 540 meters / 360 meters/second
Time = 1.5 seconds
Therefore, the train will take 1.5 seconds to cross the platform.
Hence, the correct answer is option C) 1.5 seconds.
Given:
Length of the train = 270 meters
Speed of the train = 360 meters/second
Length of the platform = 270 meters
Step 1: Calculate the time taken by the train to cross its own length
The time taken by the train to cross its own length is given by the formula:
Time = Distance/Speed
Time = 270 meters / 360 meters/second
Time = 0.75 seconds
Step 2: Calculate the time taken by the train to cross the platform
Since the length of the platform is the same as the length of the train, the train needs to cover double the distance to completely cross the platform. Therefore, the distance to be covered is 2 * 270 meters = 540 meters.
Using the formula:
Time = Distance/Speed
Time = 540 meters / 360 meters/second
Time = 1.5 seconds
Therefore, the train will take 1.5 seconds to cross the platform.
Hence, the correct answer is option C) 1.5 seconds.
