The block Q moves to the right with a  constant velocity v_0  as shown in figure.  The relative velocity of body P with  respect to Q is (assume all pulleys and  strings are ideal)

2x_P =3x_Q   ⇒  2v_P =3v_Q =3v_0        v_P =(3/2)v_0    ⇒  v_P −v_Q =(3/2)v_0 −v_0      v_(rel) =(v_0 /2) .
2xP=3xQ2vP=3vQ=3v0vP=32v0vPvQ=32v0v0vrel=v02.

let +ve direction is towards right.  v_Q =v_0   , v_P =(3/2)v_0   v_(rel)  of P with respect to Q  is = v_P −v_Q   =(3/2)v_0 −v_0 =(v_0 /2)    (+ve)  hence towards right means towards Q.
