Question

modeling real life a snowboarder descends from an elevation of 2253 feet to an elevation of 1011 feet in 3 minutes. what is the mean change in elevation per minute? the mean change in elevation is \boxed{} feet per minute.

Explanation:

Step1: Find the total change in elevation

The initial elevation is 2253 feet and the final elevation is 1011 feet. The change in elevation is initial elevation minus final elevation, so $2253 - 1011 = 1242$ feet. Since it's a descent, the change is negative, so the change in elevation is $- 1242$ feet.

Step2: Calculate the mean change per minute

To find the mean change per minute, we divide the total change in elevation by the time in minutes. The time is 3 minutes. So we calculate $\frac{-1242}{3}$.
Dividing - 1242 by 3 gives - 414.

Answer:

-414
