Answer 1

To find the rate of change in the balloon’s altitude, we need to calculate the change in altitude and then divide it by the time taken.

1. Change in altitude:
   Final altitude - Initial altitude = 200 feet - 50 feet = 150 feet.

2. Time taken:
   7 minutes.

3. Rate of change in altitude:
   Rate = Change in altitude / Time = 150 feet / 7 minutes ≈ 21.43 feet per minute.

So, the rate of change in the balloon’s altitude can be represented as 21.43 feet per minute.

The correct response is: 21.43 feet per minute.
