1.  Time (sec) 5 10 15 20 Distance (ft) 11 22 33 44

Beth and Amy are racing to see who can ride a tricycle the fastest. 7-19 HW eTool (Desmos). Homework Help ✎

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

2. What is Beth’s rate of travel?

3. If Amy travels at a rate of 75 feet per 30 seconds, would the line representing her distance and time be steeper or less steep than the graph of Beth’s rate? Explain your reasoning.

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.
$\frac{75\ \text{feet}}{30\ \text{seconds}}=2.5 \frac{\text{feet}}{\text{second}}$
