You know where balls 1 and 2 start. Since you have the velocity of each ball you can say where it is if you know how long it has been in motion. Since the two balls collide (or are at the same coordinates) you can find out where they are when they meet.

For instance, ball 1 has the equation

$\displaystyle d_{1x} = 1 + (1)t$

$\displaystyle d_{1y} = 0 + (0.300)t$

Find the components for ball 2 and solve for t by equating $\displaystyle d_{1x} = d_{2x}$ or you can do the y components.
