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?
