Step-by-step explanation:
From the question, we are informed that Swimmers best time in event is 53.87 seconds and that on average, his best time decreases by 0.28 seconds each of the next five times he swims the event.

= 53.87 - 5(0.28)
= 53.87 - 1.4
= 52.47 seconds
This means that he accomplish his goal of swimming the event in less than 52.5 seconds.
