Answer 2

hello users.......

given that
P and Q start walking around a circular track from same point. P walks in CW direction and Q in ACW

and also
P completes 4 rounds in an hour
& Q completes 5 rounds in an hour

=> speed of P is = 4 rounds per hour
&
speed of Q is = 5 rounds per hour

solution:-
to get answer
let suppose that Q is at rest and P is moving
then the relative speed of P = 4+5 = 9 rounds per hour

in 1 hour P will complete = 9 rounds
in 1 minute P will complete = 9/60 rounds
in 40 minutes P will complete = 9×40/60

= 6 rounds

hence
In 40 minutes P and Q meet each other = 6 times
