The distance between two cities P and Q is 300km. A train starts from station P at 10 am with speed 80 km/hr towards Q. Another train starts from Q towards P with speed 40km/hr at 11 am . At what time do they meet.

12.20pm

12.40 pm

12.50 pm

1 pm

Explanation:

First train starts at 10am so in one hour it covers 80 km in one hour. Now distance b/w P and Q is 220. Suppose at some’ x’ km they meet. So,
x/80 = (220-x)/40
x = 440/3.
The time after which they meet = (440/3)/80 = 11/6 i.e = 1hr 50 min.
