The table shows the distance in terms of hours Jerry and Michelle have traveled on the way to visit their family. They take turns driving for 12 hours. What distance will they travel in that time?

To determine

To use the table to write an equation and answer the given question.

Answer to Problem 15P

  $y=67x$

The distance travelled in 12 hours is 804 miles.

Explanation of Solution

Given information :

  

First we shall determine the distance travelled per hour.

Distance travelled per hour$=\frac{134-67}{2-1}=67$ miles.

Now let us assume total distance be $y$ travelled in $x$ hours.

Hence the equation shall be,

  $y=67x$

Now total distance travelled in 12 hours is,

Put $x=12$

  $\begin{array}{l}y=67\left(12\right)\\ y=804\end{array}$

Hence the distance travelled in 12 hours is 804 miles.
