Beth and Amy are racing to see who can ride a tricycle the fastest.

Graph the data about Beth’s travel that is recorded in the table at right.

Time should be on the

*x*-axis.

| Time, column 15 | Time, column 210 | Time, column 315 | Time, column 420 |

| Distance, column 111 | Distance, column 222 | Distance, column 333 | Distance, column 444 |

What is Beth’s rate of travel?

Rate is distance divided by time.

2.2 feet per second

If Amy travels at a rate of

feet per seconds, would the line representing her distance and time be steeper or less steep than the graph of Beth’s rate? Explain your reasoning.

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 points (0, 0) and (2, 5).
