A skateboarder descends on a ramp from 172 feet to 67 feet in 15 seconds.What is average change in height per second?
(172 - 67) / 15 = _____ feet per second
To find the average change in height per second, you need to calculate the difference in height divided by the time taken. In this case, the skateboarder descends from 172 feet to 67 feet in 15 seconds.
First, subtract the initial height from the final height:
172 feet - 67 feet = 105 feet
Then, divide the difference in height by the time taken:
105 feet / 15 seconds = 7 feet per second
Therefore, the average change in height per second for the skateboarder is 7 feet per second.
