Answer 2

Let's denote 3 pm by \(t = 0\). We'll now be counting in minutes.

aka car A travels at 0.75 mi/min and car B travels at 1 mi/min

can you use math to figure out the coordinates of both cars at a general time \(t\)? denote the intersection by the origin \(0, 0\)

Answer 3

i thought of using a RTD table
