| A and B are two stations 390 km apart. A train starts from A at 10 am and travels towards B at a speed of 65 kmph. Another train starts from B at 11 am and travels towards A at 35 kmph. At what time do they meet?

A. 3 : 45 pm

B. 2 : 35 pm

C. 3 : 12 pm

D. 2 : 15 pm

### Right Answer is: D

#### SOLUTION

Suppose they meet at x hours after 10 am

Then ,

Distance moved by first in x hrs + distance moved by second in ( x – 1) hrs = 390

∴ 65 x + 35 ( x -1) = 390

⇒ 100 x = 425

⇒ x =

So they meet 4 hrs 15 min after 10 am

The time is 2 : 15 pm
