Question

To avoid a storm, a passenger jet pilot descended 0.34 mile in 4 minutes. What was the plane's average change of altitude per minute?

a) 0.085 mile/minute
b) 0.14 mile/minute
c) 0.17 mile/minute
d) 0.25 mile/minute

Answer 1

The plane's average change of altitude per minute is calculated by dividing the total descent of 0.34 mile by the time taken of 4 minutes, resulting in 0.085 mile per minute.

Step-by-step explanation:

To find the plane's average change of altitude per minute, we divide the total change in altitude by the total time taken for the descent. In this case, the pilot descended 0.34 mile in 4 minutes.

The average change of altitude per minute is calculated as follows:

• Total descent: 0.34 mile
• Time: 4 minutes
• Average change of altitude per minute = (Total descent) / (Time)

Therefore, Average change of altitude per minute = 0.34 mile / 4 minutes = 0.085 mile/minute.

The correct answer to the question is option (a) 0.085 mile/minute.
