A pilot is flying an airplane. Due to strong winds, the pilot decides to fly 4,000 feet lower to avoid excessive turbulence. It takes the pilot 3.5 minutes to make this adjustment. Interpret the quotient to describe the rate of change in the plane’s altitude. Give your answer to the nearest hundredth, and remember the plane is descending.
My answer: The quotient that best represents the rate of change in the plane’s altitude is 1,142.86 feet/minute.

A recipe calls for 2 1/3 cups of oatmeal. You double the recipe and then divide it evenly into 14 servings. How much oatmeal is in each serving?
Correct Answer: 2/7 cups
All the other answers provided earlier are correct.
Hmmm. Check your oatmeal response again. Do a process, and make sure it’s correct!
Apologies for the mistake. Let's go through the process to find the correct answer:
A recipe calls for 2 1/3 cups of oatmeal. You double the recipe and then divide it evenly into 14 servings.
Step 1: Double the recipe
2 1/3 + 2 1/3 = (4+4) 2/3 = 8 2/3 cups
Step 2: Divide it evenly into 14 servings
8 2/3 ÷ 14 = 62/3 ÷ 14 = (62 ÷ 3) ÷ 14 = 20 2/3 ÷ 14
Now, let's simplify the fraction and divide:
20 2/3 ÷ 14 = 20 + 2/3 ÷ 14 = 20 + (2 ÷ 3) × (1 ÷ 14) = 20 + (2 ÷ 42) = 20 + 1/21 = 20 1/21
Therefore, each serving would have approximately 20 1/21 cups of oatmeal.
I apologize for the confusion earlier.
