## Explanation

According to the question “A goods train runs at the speed of 72 km/h and crosses a 250m long platform in 26 seconds”.

Suppose the length of the train = y

Total length = y + 250

Speed is given but needed to be converted to m/sec and time is also given (26 sec).

Length of the train will be find out easily by substituting the values in the formula mentioned below;

y + 250 = speed x time

## To Find

Length of the goods train = ?

## Solution

Given speed = 72 km/h

Speed in m/sec = (72 x 1000)/3600

Speed in m/sec = 20 m/sec

Let suppose

length of the train = y

so, total length = y + 250

Now,

length = speed x time

y + 250 = 20 x 26

y = 520 – 250

### Conclusion

If a goods train runs at the speed of 72 km/h and cross a 250m long platform in 26 seconds then the length of the goods train will be 270 meter.
