I really need help with this problem, can you also explain the R=2H, it's the part that confuses me the most, thanks!

Problem 2
A ball is thrown at an initial velocity of vo making an angle with the horizontal. At its
maximum height H, the magnitude of its velocity is 15 m/s. The horizontal range R of the ball
is twice the maximum height (that is R = 2H). (a) For how long is the ball in flight? (b) What
is the magnitude and direction of the ball's initial velocity vo?
