Homework Help: Calculus

A steady wind blows a kite due west. The kite's height above ground from horizontal position x = 0 to x = 60 ft is given by y = 150 − 1/40(x − 50)^2.
Find the distance traveled by the kite. (Round your answer to one decimal place.)

THe answer is supposed to be 94.2 ft but I cannot get to that.
Also I am not really familiar with the sinh and cosh functions so please be really specific.

Not enough info here. Is the kite supposed to have flown from some point to another? Fallen to the ground? Reached steady state at some height? what?
