Her fastest change in elevation was -200 feet in 10 minutes. She was going at a rate of 20 fpm (feet per minute) compared to 15 fpm.
Because y varies inversely as x, therefore

where k = constant.
When x = 6, y = 2.5. Ther efore

Cross multiply.
k = 6 x 2.5 = 15
The equation is

When x = 4, obtain

Answer: a. 3.75
For this case we have the following equation:

We must solve the equation by following the steps below:
We subtract 1 from both sides of the equation:

On the right side of the equation we have that different signs are subtracted and the sign of the major is placed:

We add x to both sides of the equation:

We divide between 4 on both sides of the equation:

Thus, the correct option is option B
