An airplane is flying at a speed of 350 mi/h at an altitude of one mile and passes directly over a radar station at time t=0.
a) Express the horizontal distance d (in miles) that the plane has flown as a function of t.
b) Express the distance s between the plane and the radar station as a function of d.
I used the pythagorean theorem to get 1^2 + (350t)^2= sqrt of (1^2+d^2)^2
Is that right? If I solve for t it gives me zero.
c) Use composition to express s as a function of t.
Please Help. Explanations also would be nice, so I can see how to do it.
