#### Answer

a. The speed of object A is faster than the speed of object B at t = 1 s.
b. The speed of object A is faster than the speed of object B at all times t.

#### Work Step by Step

a. At time t = 1 s, the slope of graph A is larger than the slope of graph B. Therefore, the speed of object A is faster than the speed of object B at time t = 1 s.
b. The slope of graph A is constant and the slope of graph B is constant, so the speeds of both objects are constant. The slope of graph A is larger than the slope of graph B. Therefore the speed of object A is faster than the speed of object B at all times t.
