Answer:We can start by using the formula:

distance = rate x time

Suzanne walks at a rate of 1.3 m/s for 2.0 s, so her total distance traveled is:

distance = 1.3 m/s x 2.0 s = 2.6 m

Since Suzanne is walking towards a mirror, her image in the mirror is the same distance away as she is from the mirror. After 2.0 s, Suzanne will have traveled a total distance of 2.6 m towards the mirror, so she will be:

distance from mirror = starting distance - distance traveled

distance from mirror = 5.0 m - 2.6 m

distance from mirror = 2.4 m

Therefore, Suzanne is 2.4 m away from her image in the mirror after 2.0 s.
