Jade and her roommate Jari commute to work each morning, traveling west on I-10. One morning Jade left for work at 6:50 A.M., but Jari left 10 minutes later. Both drove at a constant speed. The following graphs show the distance (in miles) each of them has traveled on 1-10 at time (i minutes), where t = 0 is 7:00 A.M. y 30 Distance 20 travled (mi) 2 4 6 8 10 12 Time Since 7:00 A.M.
