Question

to avoid a storm, a passenger-jet pilot descended 0.76 mile in 0.8 minute. what was the planes average change of altitude per minute? the average change in altitude was \boxed{} mile(s) per minute.

Explanation:

Step1: Recall the formula for average rate

The average rate of change (in this case, average change of altitude per minute) is calculated by dividing the total change in altitude by the total time taken. The formula is:
\( \text{Average rate} = \frac{\text{Change in altitude}}{\text{Time taken}} \)

Step2: Substitute the given values

We know the change in altitude is \( 0.76 \) miles and the time taken is \( 0.8 \) minutes. Substituting these values into the formula, we get:
\( \text{Average rate} = \frac{0.76}{0.8} \)

Step3: Perform the division

To divide \( 0.76 \) by \( 0.8 \), we can multiply both the numerator and the denominator by \( 100 \) to eliminate the decimals (or directly perform the division).
\( \frac{0.76}{0.8} = \frac{76}{80} = 0.95 \) (We can also do this division as \( 0.76 \div 0.8 = 0.95 \) by moving the decimal points appropriately or using long division.)

Answer:

\( 0.95 \)
