Final answer:

The jet takes approximately 13.2 minutes to descend 5,280 feet.

Step-by-step explanation:

To find out how long it takes for the jet to descend 5,280 feet, we can set up a proportion based on the information given.

Since the jet takes 10 minutes to descend 4,000 feet, we can set up the proportion:

10 minutes / 4,000 feet = x minutes / 5,280 feet

Cross-multiplying and solving for x, we get:

x = (10 minutes * 5,280 feet) / 4,000 feet

x = 13.2 minutes

Therefore, it takes the jet approximately 13.2 minutes to descend 5,280 feet.
