The answer is 2 s.
Imagine the squre ABCD as given in the question.
P-> 2m/s and Q -> 10m/s
In 1 sec:
P at point A moves 2 meters along the 8m long arm AD of the square.
Q at point B moves 10 meters, which in the square would be BC 8m plus CD 2 meters.
In the next second:
P moves another 2 meters making a displacement of 4m along AD.
Q moves another 10 meters. (6m further along CD and 4 m along DA) and meets P.
