Anita and Brad are each riding on the same bicycle path. They both start riding at the same time, in the same direction. Anita began riding at the start of the path and Brad began from a spot 10 miles ahead of her. The equations below represent their distance along the path in kilometers, y, over time in hours, x. •Anita: y=18x
•Brad: y=13x+10

After how many hours do Anita and Brad meet on the path?
