# Find the Distance Between Stations A and B.

Form stations A and B, two trains start moving towards each other with the speeds of 150 km/h and 130 km/h, respectively. When the two trains meet each other it is found that one train covers 20 km. more than that of another train. Find the distance between stations A and B.

- 20 km
- 120km
- 280 km
- None of these

**Answer: (3) 280 km**

**Explanation:-**

Let be the distance covered by the first train = X km

And distance covered by second train = (X + 20) km

Then ,

X/130 = (X + 20)/150

by cross multiplication,

150X = 130X + 130 x 20

150X – 130X = 2600

20X = 2600

X = 2600/20

X = 130 km

Total distance = X + X + 20 = 130 + 130 + 20

= 280 km

Hence, the answer is (3) 280 km.
