Step 1

Find the equation of the line.

First, pick two points.

(2.5, 100) and (5, 200)

Step 2

Find the slope


\begin{gathered} \text{Slope m = }(y_2-y_1)/(x_2-x_1) \\ m\text{ = }\frac{200\text{ - 100}}{5\text{ - 2.5}} \\ m\text{ = }(100)/(2.5) \\ m\text{ = 40} \\ i\text{ntercept c = 0} \\ \text{The equation of a line is:} \\ y\text{ = mx + c} \\ y\text{ = 40x} \end{gathered}

y represent distance and x represent time

The distance traveled after 15 hours = 40 x 15 = 600
