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?
Answer
A
The independent variable is distance and the dependent variable is time.
B
The independent variable is time and the dependent variable is distance.
C
The independent variable is distance and the dependent variable is speed.
D
The independent variable is speed and the dependent variable is distance.
Explanation
In the equation d = 0.5 + 5t, the distance d changes according to the jogging time t. Time is the independent variable, and total distance is the dependent variable. Therefore, choice B is correct.
