### Question

A train running at 8km/h leaves a railway station 18 hours later than another train, and meets it in 6 hours. What is the speed of the other train?

**A**

2 km/h.

**B**

3 km/h.

**C**

5 km/h.

**D**

4 km/h.

**Soln.**

**Ans: a**

Let the speed of the train be v km/h. Distance travelled by this train in (6 + 18) hours = 24v km. Equating this to the distance travelled by the second train we get 24v = 8 × 6, which gives v = 2 km/h.
