**bobpursley**, Thursday, December 2, 2010 at 9:44pmThe balloon travels 14mi/hr*t/3600 where t is in seconds. I suppose it would be better to change the velocity to ft/sec

Memorize this conversion factor 60mph=88fps

the balloon travels then 14/60*88 t feet.

the triangle then yields a slant height of

distance= sqrt (120^2+(14*88/60 t)^2 )
