Not the only method:
              SPEED          TIME          DISTANCE

LATE            b/h            h              b

ON-TIME         b%2Fh%2Bx         b%2F%28b%2Fh%2Bx%29          b

DIFFERENCE                      2

h-%28b%2F%28b%2Fh%2Bx%29%29=2----------simplify and solve for x.
Use this x to substitute and simplify the ON-TIME speed expression.
