## Explanation

In what time will a train 100 meters long cross an electric pole? The length of train is 100 m but given speed is 144 km/h so we will do a couple of things here.

In the first step, we will change speed from km/h to m/sec and then,

Time = Distance/Speed

Time = ?

## Solution

Given speed = 144 km/h

Speed in m/sec = (144 x 1000)/3600

Speed in m/sec = 40 m/sec

Now,

Time = distance/speed

Time = 100/40

### Conclusion

If speed is 144 km/h then a train 100 meters long will cross an electric pole in 2.5 seconds.
