One morning Jade left for work at 6:50 a.m., 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 a.m. 25 20 (6, 16) Jade Distance traveled (mi) 15 10 (6, 8) Jari 5 2 4 6 8 10 Time since 7:00 AM (min) (a) Use the graph to decide which driver is traveling faster. O Jade O Jari (b) Find the speed (in mi/h) at which each of them is driving. Jade mi/h Jari mi/h (c) Find linear functions f and g (in miles) that model the distances traveled by Jade and Jari as functions of t (in minutes). Jade f ( t ) = mi Jari g(t) = mi Need Help?
