To find the rate of change in the goat's elevation, we need to calculate the elevation change per unit of time.
The goat climbs a cliff that is 50 feet high in 22 minutes. To find the rate of change in elevation, we will divide the total elevation gained by the total time taken:
\[ \text{Rate of change} = \frac{\text{Total elevation gain}}{\text{Total time}} = \frac{50 \text{ feet}}{22 \text{ minutes}}. \]
Now, we can calculate this quotient:
\[ \text{Rate of change} = \frac{50}{22} \approx 2.27272727. \]
To round this to the nearest hundredth, we look at the third decimal place (which is 2 in this case). Since it is less than 5, we leave the second decimal place as it is.
Thus, rounding gives us:
\[ \text{Rate of change} \approx 2.27 \text{ feet/minute}. \]
So, the final answer is:
2.27 feet/minute.
