Question

The distance between 2 cities A and B is 330 km. A train starts from A at 8 am and travel towards B at 60 km/hr. Another train starts from B at 9 am, and travels towards A at 75 km/hr. At what time do they meet?

Answer 1

They meet at 11 am because ......

Suppose they meet x hrs after 8 a.m. 
then
(Distance moved by first in x hrs) + [Distance moved by second in (x-1) hrs]
= 330
So, 60x+75(x-1) = 330 

x=3.

So,they meet at (8+3). i.e 11a.m.
