You are riding your bike down a long, straight road and you have your cell phone in your pocket. The GPS in your phone records your position at certain increments of time, and when you're home, an app tells you how far along the road you were as a function of time. Calculate the average velocity of your bike ride over the following intervals. time (in minutes) 5 10 15 20 25 30 distance from home (in miles) 0 1 1.7 3 2.2 1.1 0.4 (a) [0, 15] (b) [0, 15] (c) [5, 15] (d) [10, 15] (e) [15, 30] (f) [15, 25] (g) [15, 20]
