Jade and her roommate Jari commute to work each morning, traveling west on I-10. One morning Jade left for work at 6:50 am, but Jari left 10 minutes later. Both drove at a constant speed. The graphs show the distance (in miles) each of them has traveled on I-10, t minutes after 7:00 am.
(a) Use the graph to decide which driver is traveling faster.
(b) Find the speed (in mi/h) at which each of them is driving.
(c) Find linear functions f and t that model the distances traveled by Jade and Jari as functions of t (in minutes).
