Consider one particle is moving in direction of +ve x axis with velocity v1 and other in direction of -ve x axis with velocity v2.
At time t,velocities of two bodies are:
v1=(3)i - (10t)j
v2=(-4)i - (10t)j
When velocity vectors are perpendicular ,v1.v2=0
So, -12+100t2=0
or t=√3/5

but they're asking for the distance, not the time
