this is when its solved: r=4, s=3}
Isolate the term that has v :
5 v/9 =z-w
Multiply both sides by 9:
5v =(z-w)•9
Divide both sides by 5:
v= (z-w)•9/5
We use the formula
where d is distance, s is speed and t is time.


Therefore, a car would tracel 480 km.
(-4, 1)
the solution is always where the two points meet!! :)
