Question:

Starting at the same point on a straight road, Anna and Benny begin running with velocities (in mi/hr) given by vA(t) = 2t + 1 and vB(t) = 4 - t, respectively. 

a. Graph the velocity functions, for 0 ≤ t ≤ 4.

b. If the runners run for 1 hr, who runs farther? Interpret your conclusion geometrically using the graph in part (a).

c. If the runners run for 6 mi, who wins the race? Interpret your conclusion geometrically using the graph in part (a).
