Don left Vancouver and drove towards Hope BC at a speed of 120 km/h. Brad left Hope at the same time and drove towards Vancouver at a speed of 90km/h. If Hope is 122 km from Vancouver how far had they each driven when they passed each other on the highway?

The first problem: 
              SPEEDS       TIME               DISTANCES

Carrier        r+5          450/(r+5)             450

Ship            r           300/r                 300

450%2F%28r%2B5%29=300%2Fr-----------"in the same amount of time"
