Projectile Motion Question?

A physics professor is attempting to jump across a river on a motorcycle. The takeoff ramp was inclined at 53 degrees, the river was 40 m wide, and the far bank was 15 m lower than the top of the ramp. Ignoring air resistance, a) what should his speed have been at the top of the ramp to have just made to the far edge of the bank. If his speed was only half the value found in a), where did he land?
