Noelle and karina both leave the Internet cafe at the same time, but in opposite directions. If karina travels 9 mph faster than noelle and after 8 hours they are 232 miles apart, how fast is each traveling?
Noelle goes east at N mph. Karina travels west at N + 9 then their velocity between them is (N + N + 9) After 8 hours they travel 8(2N + 9) = 232 (2N + 9) = 29 2N = 20 N = 10 mph for Noelle N+9=19 mph for Karina
