two cars leave the station at 9:00 am. the first car head due south at an avg speed of 54mph. the second car heads due west at an avg speed of 72mph. how far apart will the cars be at 1:00pm?
my solution: 360mi is this correct
Car 1 goes 216 miles south in 4 hours.
Car 2 goes 288 miles west in 4 hours.
The vector distance between them is then the hypotenuse of a right trangle, with length 360 miles.
Note that the sides of the triangle are in an exact 3:4:5 ratio.
Congratulations! Good work
