#### Answer

Consider the function $d=50t,$ where $d$ represents distance and $t$ represents time. The value of $d$ depends on the value of $t,$ so the variable $t$ is the $\underline{\text{
dependent variable
}},$ and the variable $d$ is the $\underline{\text{
independent variable
}}.$

#### Work Step by Step

Use the definitions of dependent and independent variables.
