# What will be the Distance Between Two Station?

A train starts from station A and reaches B 15 minutes late when it moves with 40 km/hr and 24 minutes late when it goes 30 km/hr. The distance between the two station is

- 21 km
- 18 km
- 24 km
- 16 km

**Answer: (2) 18 km**

**Explanation:-**

Let the distance between two station be X km.

According to the question,

X/40 + 15/60 = X/ 30 + 24/60

X/ 40 – X/ 30 = 2/ 5 – 1/ 4

(3 X – 4 X) / 120 = (2 x 4 – 1 x 5)/20

– X / 6 = 3

X = 3 x (-6)

X = – 18

X = 18 km (distance is always possible )

Then, the distance between two station is 18 km.

Hence, the answer is (2) 18 km.
