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 feet every second. Victor's rate of change is square That means that his height in the air decreases square feet every second.

To determine who was descending at a faster rate, we need to calculate the rate of change for both Mel and Victor.

For Mel:
Given points: (2, 50) and (5, 35)
Rate of change = (change in height) / (change in time)
Rate of change = (35 - 50) / (5 - 2)
Rate of change = -15 / 3
Rate of change = -5 feet per second

For Victor:
Given points: (1, 60) and (4, 50)
Rate of change = (change in height) / (change in time)
Rate of change = (50 - 60) / (4 - 1)
Rate of change = -10 / 3
Rate of change = -3.33 feet per second

Therefore, Mel's rate of change is -5 feet per second, which means her height in the air decreases by 5 feet every second. Victor's rate of change is -3.33 feet per second, which means his height in the air decreases by 3.33 feet every second.

So, Mel was descending at a faster rate than Victor.
