Calculate the unit rate from the graph.270Mi les18090N6GO10Hoursmiles per hour

Answer 1

The unit rate from the graph is given by the slope of the straight line graph

To find the slope, we need two pick any two points on the line, say

`\begin{gathered} (t_(1,)d_1)\text{ and }(t_(2,)d_2) \\ \text{then} \\ \text{slope = }(d_2-d_1)/(t_2-t_1) \end{gathered}`

We pick the points (0,0) and (4, 240)

`\text{slope}=(240-0)/(4-0)=(240)/(4)=60`

Therefore the unit rate from the graph is 60miles per hour
