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.
