Answer
Correct Answer: 89 seconds
Explanation
We are given:
- Length of train = 240 m
- Time to pass a pole = 24 seconds
- Length of platform = 650 m
Step 1: Find speed of the train
Speed = Distance / Time= 240 / 24 = 10 m/s
Step 2: Calculate total distance to pass the platform
Total distance = train length + platform length= 240 + 650 = 890 m
Step 3: Calculate time to pass the platform
Time = Distance / Speed= 890 / 10 = 89 seconds
Final Answer:
The train will take 89 seconds to pass the platform.
