VECTORS QUESTION!

you are driving from point a(24,96) on a map grid toward point B with a velocity defined by d vector (85, -65) km/h
i) state the parametric equations of the highway line
i know this.. x=24+85t
y=96-65t, t is an element of the real numbers.
ii) how long have you been travelling when you reach a point P 102 km east of where you started a point a?
iii) What are the coordinates of your position P at that time?

I believe you set {x} = 24 + 102, because it does ask for 102km east of your original position. Then, solve for t, which will be in hrs.

Part 3) Plug in the value of t you found into {y} to find that y-value of your position P.
