Travel You begin a long-distance trip along the highway at mile marker 21. After 5 minutes, you pass mile marker 32. After another 5 minutes, you pass mile marker 43. You have been traveling at a constant rate. If you continue to travel at this constant rate, what mile marker will you be at after 60 minutes? (Hint: Consider marker 21 (after 0 minutes) to be a1, marker 32 (5 minutes) to be a2, marker 43 (after 10 minutes) to be a3, and so on.)
