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?

1- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis.2- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in the first question?
