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

Answer 1

When an equation is solved for a variable y in terms of a variable x, i.e. the usual y=f(x) form, then x is the independent variable and y is the dependent variable.

In your case, the equation is written as d=f(t), so t is the independent variable and d is the dependent variable.
