Car A and Car B get on the freeway at the same time and the same point.
They are traveling at different speeds, but each car is maintaining its own consistent speed.
After a few minutes, Car A is at mile marker 10 and Car B is at mile marker 17.
When Car B reaches mile marker 85, at which mile marker is Car A?
:
let m = car A's 2nd mile marker
m%2F85 = 10%2F17
cross multiply
17m = 85 * 10
17m = 850
m = 850%2F17
m = 50 mile marker is Car A's 2nd marker
