# What is the Length of Second Train? If

Two trains cross each other in 1 minute moving in the same direction at the speeds of 40 km/hr. and 22 km/hr respectively. If the length of the first train is 125 metres, find the length of the second train?

- 250 metres
- 300 metres
- 175 metres
- None of these

**Answer: (3) 175 m**

**Explanation:-**

Let the length of the second train = X m.

The speeds of the train = 40 km/hr. and 22 km/hr.

According to the question,

(125 + X ) / (40 – 22) x 5/28 = 60

(125 + X) x 18 /18 x 5 = 60

(125 + X) / 5 = 60

125 + X = 60 x 5

125 + X = 300

X = 300 – 125

X = 175

Then, the length of the train is 175 m

Hence, the answer is (3) 175 m.
