## Explanation

â€śA train 240 meter long passes a pole in 24 secondsâ€ť, this statement shows two quantities are given i.e.

- Length
- Time

Both these quantities are sufficient to find out the speed.

And, the total length becomes 240 + 650 = 890 meter. So;

Time = Distance/Speed

## To Find

Time = ?

## Solution

Length of train = 240 m

Time required to pass a pole = 24 sec

Speed in m/sec = 240/24 = 10 m/sec

Total length = 240 + 650 = 890 meter

Now,

Time = distance/speed

Time = 890/10

**Time = 89 seconds answer**

### Conclusion

A train 240 meter long passes a pole in 24 seconds. It will take **89 seconds** to pass a platform 650 meter long.
