From the question: P takes 8 hours and Q takes 7 hours. Suppose total distance = a ⇒ Speed of P = a/8 Speed of Q = a/7 And Relative speed = a/8 + a/7 = 15a/56
|
Now, Distance covered by P till 8 am (When Q starts the journey) = 2a/8 = a/4 Then, Remaining distance = a – a/4 = 3a/4 Time after 8 pm when they will meet = (3a/4)/(15a/56) = 14/5 hours = 2 hours 48 minutes Hence, time = 10:48 am |
