Verified Answer
A train having a length of 240 m passes a post in 24 seconds. How long...
Speed = 240/24 m/sec
= 10m/sec
∴ Requiredtime = (240+650)/10sec.
= 89sec.
= 10m/sec
∴ Requiredtime = (240+650)/10sec.
= 89sec.

A train having a length of 240 m passes a post in 24 seconds. How long...
To solve this question, we need to find the time taken by the train to pass the platform.
Given:
Length of the train = 240 m
Time taken to pass a post = 24 seconds
Length of the platform = 650 m
Let's calculate the relative speed of the train with respect to the platform.
Relative speed = Distance/Time
The distance covered by the train to pass the post is equal to its length, which is 240 m. The time taken to cover this distance is given as 24 seconds. Therefore, the relative speed of the train is:
Relative speed = 240 m/24 s = 10 m/s
Now, let's calculate the time taken by the train to pass the platform.
The train needs to cover its own length (240 m) and the length of the platform (650 m). Therefore, the total distance it needs to cover is:
Total distance = Length of train + Length of platform = 240 m + 650 m = 890 m
Using the relative speed calculated earlier, we can find the time taken by the train to cover this distance:
Time taken = Distance/Relative speed = 890 m/10 m/s = 89 seconds
Therefore, it will take 89 seconds for the train to pass the platform.
Hence, the correct answer is option 'C' (89 seconds).
Given:
Length of the train = 240 m
Time taken to pass a post = 24 seconds
Length of the platform = 650 m
Let's calculate the relative speed of the train with respect to the platform.
Relative speed = Distance/Time
The distance covered by the train to pass the post is equal to its length, which is 240 m. The time taken to cover this distance is given as 24 seconds. Therefore, the relative speed of the train is:
Relative speed = 240 m/24 s = 10 m/s
Now, let's calculate the time taken by the train to pass the platform.
The train needs to cover its own length (240 m) and the length of the platform (650 m). Therefore, the total distance it needs to cover is:
Total distance = Length of train + Length of platform = 240 m + 650 m = 890 m
Using the relative speed calculated earlier, we can find the time taken by the train to cover this distance:
Time taken = Distance/Relative speed = 890 m/10 m/s = 89 seconds
Therefore, it will take 89 seconds for the train to pass the platform.
Hence, the correct answer is option 'C' (89 seconds).
