Mel slides down waterslide A, and Victor slides down waterslide B. After 2 seconds, Mel was 50 feet in the air, and after 5 seconds, she was 35 feet in the air. After 1 second, Victor was 60 feet in the air, and after 4 seconds, he was 50 feet in the air. Who was descending at a faster rate? Mel: 2,50 and 5,35 Victor: 1,60 and 4,50 Mel's rate of change is square . That means that her height in the air decreases square second. feet every Victor's rate of change is square That means that his height in the air decreases square feet every second. DONE

Answer:Mel was descending at 5 feet per second and Victor was descending at 3.33 feet per second, thus Mel was descending faster.Since after 2 seconds, Mel was 50 feet in the air, and after 5 seconds, she was 35 feet in the air, while after 1 second, Victor was 60 feet in the air, and after 4 seconds, he was 50 feet in the air, to determine who was descending at a faster average rate and what is Mel's rate of change, the following calculations must be performed:You must subtract the difference between the two times for each person, and check which is the highest rate between the two.Mel =(50 - 35) / (5 - 2) = X15/3 = X5 = XVictor =(60 - 50) / (4 - 1) = X10/3 = X3.33 = XTherefore, Mel was descending at 5 feet per second and Victor was descending at 3.33 feet per second, thus Mel was descending faster.
