7. Michael swims laps in the pool at the local recreational center. The pool is 25 yards long and it takes him about 21 seconds to get from one side to the other. The graph shows Michael's distance from the south end of the pool during his swim. a. Find the coordinates of Point B and interpret your answer In the context of this problem, Dista b. Find the coordinates of Point D and interpret your answer in the context of this problem, Time (seconds) C. At points A and C, Michael is 18.75 yards away from the south end of the pool, How many seconds have passed between Point A and Point C? Give a reason for your answer. d. Approximate the next time after Michael is at Point A that he is 18.75 yards away from the south end of the pool. e. Callie says that since Michael swims 25 yards every 21 seconds, he must be swimming at a constant rate. Do you agree or disagree? Explain
