A train 240 m long passes a pole in 24 seconds. How long will it take to pass a platform 650 m long?

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.
