Jade and her roommate Jari commute to work each moring, traveling west on I-10. One morning Jade left for work at 6:45 A.M., but Jari left 15 minutes later. Both drove at a constant
speed. The folowing graphs show the distance (in mies) each of them has traveled on 1-10 at time t (in minutes), where (= 0 is 7:00 A.MI
