-
Length of the train = 240 meters
-
Time to pass a pole = 24 seconds
-
Length of the platform = 650 meters
✅ Step 1: Find the speed of the train
When the train passes a pole, it travels a distance equal to its own length.
Speed = Distance ÷ Time
= 240 m ÷ 24 s = 10 m/s
✅ Step 2: Total distance to pass the platform
= Length of train + Length of platform
= 240 m + 650 m = 890 meters
✅ Step 3: Time = Distance ÷ Speed
= 890 ÷ 10 = 89 seconds
✅ Final Answer: The train will take 89 seconds to pass the platform.
