Explanation
“A train 240 meter long passes a pole in 24 seconds”, 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.
