How Much Time is Saved in a Baseball Throw with an Infielder Relay?

[lanruoer]

Homework Statement

During a baseball game, the outfielder picks up the ball in the outfield and throws it at 45 degree above the horizontal towards home plate. the ball is caught by the catcher at the same level who is 125m away. if the outfielder had instead thrown the ball to an infielder, who is standing half way between the outfielder and the catcher, who then threw it home, how much time might have been saved? Neglect air resistance and assume all three throws have the same speed and height when thrown and caught. Also allows 0.25 s for the infielder to catch, turn, and throw.

how to set up this problem. I know that I need to use the kinematic equations, but I am not sure how to apply them in this situation.
