Question

An airplane descends at the rate of 175 ft per minute. What is the airplane's change in altitude after 5 minutes?

a) 800 ft
b) 875 ft
c) 875 ft/min
d) 200 ft

Answer 1

The airplane descends at a rate of 175 ft per minute, so after 5 minutes, the change in altitude is 175 ft/min × 5 min = 875 ft.

Step-by-step explanation:

To find the change in altitude of the airplane after 5 minutes, we'll calculate it based on the given rate of descent.

Here's the step-by-step calculation:

1. Identify the rate of descent: 175 feet per minute.
2. Identify the time of descent: 5 minutes.
3. Multiply the rate of descent by the time to get the total change in altitude: 175 ft/min × 5 min = 875 ft.

Therefore, the airplane's change in altitude after 5 minutes is 875 feet.
