Two bullets are shot with different velocity from the same gun placed parallel to an inclined plane. Which one will strike the plane first?

1. the faster

2. the slower

3. neither, both strike the plane at the same time

2. Relevant equations

Kinematics equations................

3. The attempt at a solution

It can be seen from here http://phet.colorado.edu/sims/projectile-motion/projectile-motion_en.html that both fall onto the plane at the same time but I don't know how to explain it mathematically. I think we should find the time it takes each bullet to reach its maximum height (t1), then deduce the time they travel until hitting the plane (t2), the sum of them should be an expression independent of v. I'm able to write down t1, but I'm stuck at determining t2. Any help would be appreciated.
