        You will not understand the following equations anyway...
        But here is what I did to get them.
 
        I used the functions
 
          s(t) = t * vs
          z(t) = t * vz - 1/2 grav t^2
 
        and solved for:
 
          s(ti) = sdist
          z(ti) = zdist
          max(z, ti) = jumpheight
 
        From these three equations, you will find the three parameters vs, vz
        and ti.
