My teacher says that this probable has to be set up with a variable statement, equation, and answer. I've been stuck on it for about 2 days. I'm really not sure how to set this problem up.
Thanks,

Kristi, this is kind of a trick problem. The distance between them is 500 miles, Notice how every hour, the distance between them decreases by 47+53 = 100 miles. Thus it would take them 5 hours to meet. The setup is merely 47t + 53t = 500.
