So V, left bracket, 3, right bracket, equalsV(3)=
, meaning after 33


.

Answer 1

The independent variable, x, represents the time, and the dependent variable is the distance, because the distance depends on the time.

A function relating these variables is V(x) = 55x.

So V(3) = 55(3) = 165, meaning after 3 hours, Avery will have traveled 165 miles.
