Question

Jillian walked 0.5 miles before she started jogging at an average pace of 5 miles per hour. The equation d = 0.5 + 5t can be used to relate the total distance, d, in miles to the time, t, that Jillian spent jogging. What are the independent and dependent variables?

The independent variable is distance and the dependent variable is time.
The independent variable is time and the dependent variable is distance.
The independent variable is distance and the dependent variable is speed.

Answer 2

The answer is option 2.

Explanation:

In the question, the independent variable is time and dependent is distance. As the time changes, the distance will also change it means the distance depends on time.

For example,

`d = 0.5 + 5t`

Let t = 1,

`d = 0.5 + 5(1)`

`d = 5.5 \: miles`

Let t = 5,

`d = 0.5 + 5(5)`

`d = 25.5 \: miles`

Therfore, as time increases, distance will also increase.
