Two trains travel in the same direction at and and the faster train passes a man in the slower train in seconds. Find the length of the faster train.
- A
- B
- C
- D
Solution & Step-by-step Explanation
To find the length of the faster train, we need to determine the distance covered by the faster train relative to the man in the slower train during the crossing time.
Step 1: Calculate the relative speed
Since both trains are moving in the same direction, the relative speed is the difference between their speeds:
**Step 2: Convert relative speed into metres per second ()**
Step 3: Calculate the length of the faster train
The distance covered in passing the man is equal to the length of the faster train:
Step 1: Calculate the relative speed
Since both trains are moving in the same direction, the relative speed is the difference between their speeds:
