Harry and Angela look from their balcony to a swimming pool below that is 15 m from the bottom of their building. They estimate that the balcony is 45 m high and wonder how fast they would have to jump horizontally to succeed in reaching the pool. What is the answer?

Please Help!!
Thanks! :)

    how long to fall 45 m?
    45 = (1/2)(9.8) t^2
    solve for t

    then how fast to go 15 m in t seconds?
    15 = v t
    v = 15/7
