Question

Cameron is located 2 miles due East of an intersection between two country roads. He decides to walk in a straight line (cross-country) toward a position 3 miles due North of the intersection; it takes Cameron one hour to reach that location.
(a) Find parametric equations for the location of Cameron at time t hours.

(b) Find the rate of change of the distance between Cameron and the intersection at time 15 minutes (t=1/4 hr).

Answer 1

is parametric equation same as the uniform linear motion? where x(t)=a+bt , y(t)c+dt would I use this to solve for a?

Answer 2

Yes.

X=2-2t
y=3t
