Question

Oliver and Robin have different stride lengths and want to compare them. Oliver uses a table to represent the distance he travels in feet related tothe number of strides he takes. Question 2 Using Robin's graph, how can you find the unit rate?

Answer 1

The grpah is plotted with the number of strides along the x axis and the distance travelled along the y axis.

So, the slope of the graph gives the distance travelled by Robin per stride or the stride length. The approximate value of slope of the graph is,

$\text{Slope}=\frac{\Delta y}{\Delta x}=\frac{8-0}{3-0}=\frac{8}{3}=2.67$

So, the stride length or the unit rate of Robin is approximately 2.67 feet.
