Question 730255: An airplane is flying at a speed of 350 miles/hr at an altitude of one mile. The plane passes directly above a radar station at time t=0.
a. Express the distance s(in miles) between the plane and the radar station as a function of the horizontal distance d(in miles) that the plane has flown.
b. Express d as a function of the time t (in hours) that the plane has flown.
c. Use composition to express s as a function of t.

An airplane is flying at a speed of 350 miles/hr at an altitude of one mile.
The plane passes directly above a radar station at time t=0.
a. Express the distance s(in miles) between the plane and the radar station
as a function of the horizontal distance d(in miles) that the plane has flown.
b. Express d as a function of the time t (in hours) that the plane has flown.
c. Use composition to express s as a function of t.
~~~~~~~~~~~~~~~~~~~~~~~~~~ 

(a)  The distance under question (a) is  s = sqrt%28d%5E2%2B1%29  miles.


(b)  d = 350*t.


(c)  The distance under question (c) is  s = sqrt%28350%2At%5E2%2B1%29 miles.
