Exercise 1 Page 249

Which variable causes a change in the other variable?

Independent Variable: Speed, s
Dependent Variable: Distance traveled, d

Practice makes perfect

To identify which variable is independent and which is dependent, we need to analyze which variable causes a change in the other variable.

Independent Variable: Causes change in the dependent variable.
Dependent Variable: Changes because of the independent variable.

Traveling at a higher speed s increases the distance traveled d. In other words, the distance traveled depends on the speed. Therefore, the speed is the independent variable and the distance traveled is the dependent variable.
