Optimum angle of a starting surface lower than the landing surface

1. The problem statement, all variables and given/known data
When a BMX biker is bunny hopping to a ledge that is 3.5 ft tall and 7ft away at 1.388 888 888 9 meter/second what is the optimum angle? what is the distance achieved and the hieght achieve w/ the optimum angle?

*** Please inculde the formula used***
2. Relevant equations

3. The attempt at a solution

This is not a question quoted from a textbook but a question that I came up w/ myself. I am trying to find the fromula to get the distance and height of an optimum angle. I think the optimum angle is less than 45 degrees due to the fact that the landing site is above the starting site.
