# What will be the Length of Goods Train? If

A goods train runs at the speed of 72 km/hr and crosses a 250 m long platform in 26 seconds. What is the length of the goods train?

- 230 m
- 240 m
- 260 m
- 270 m

**Answer: (4) 270 m**

**Explanation:-**

Let the length of the goods train be = X m

The speed of the goods train = 72 km/hr

Speed in m/sec = 72 x 5/18 = 20 m/sec

The length of the platform = 250 m

Total distance covered by train = (X + 250) m

Time taken by train to cross the platform = 26 sec

**Formula-**

**Time = Distance/speed**

Then, (X + 250) /20 = 26

X + 250 = 26 x 20

X = 520 – 250

X = 270 m

Hence, the length of the goods train is 270 m.
