7-18.

Time should be on the x-axis.

Rate is distance divided by time.

2.2 feet per second

Find the number of feet Amy would travel per second.

Is it larger than your answer for part (b)?

If you are still confused about which line should be steeper, try plotting

a line on your graph from part (a) to represent Amy's rate of travel.

The line should pass through the point (0, 0) and have a slope of 2.5.

Use the eTool below to graph the data about Beth's travel.
