the distance traveled by the ball is given by
D(t)=-5t^2+115t-110 (in feet)
how far will the ball travel before it hits the ground?

at what level is ground?
this informations I have:
The Physics of Baseball by Robert Adair -
after t seconds, starting 1 sec after 35 angle, rotating with an initial backspin of 2000 revolutions per minute, and hit about 110mph is given by
H(t)= -80t^2+340t-260 (in feet)
a)how many seconds willpass before the ball hits the ground?
The distance travelded by the ball is given by
D(t)= -5t^2+115t-110 (in feet)
b)How far will the ball travel before it hits the ground?
c)Using D(t), how far will a ball travel in 6 seconds, the time it takes it takes a high fly ball to hin the ground?
