Answer

a. The speed of A is greater than the speed of B at time t = 1 s. b. At time t = 3 s, the speed of A is the same as the speed of B.

Work Step by Step

a. At time t = 1 s, the slope of graph A is greater than the slope of graph B. Therefore the speed of A is greater than the speed of B at time t = 1 s. b. At time t = 3 s, the slopes of the two graphs are equal. Therefore, at time t = 3 s, the speed of A is the same as the speed of B.
