Well first consider the time it takes to hit the dart board..

then consider the vertical movement of the object (hint: what is the dart's initial vertical velocity?) and think gravity (constant acceleration......)... then how far it moved (vertically) in the time it takes to strike the dartboard...

can't say much more or I'd be giving the answer away....
