Question
**Problem:** A skateboarder descends on a ramp from 172 feet to 67 feet in 15 seconds. What is the mean change in height per second? ____________ **Solution Approach:** 1. Calculate the total change in height by subtracting the final height from the initial height: - \( 172 \text{ feet} - 67 \text{ feet} = 105 \text{ feet} \) 2. Divide the total change in height by the total time to find the mean change in height per second: - \( \frac{105 \text{ feet}}{15 \text{ seconds}} = 7 \text{ feet per second} \) So, the mean change in height per second is 7 feet.
