Your grandparents live 100 miles away from you. If your parents drive at an average rate of 30 mph, the distance from you to your grandparents’ house can be modeled by the equation d = 100 – 30h, where d is the distance from your grandparents’ house in miles and h is the number of hours you’ve been driving. Graph this function and see how far from your grandparents’ house you will be after 2 hours.
