7-19.

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

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

Time should be on the x-axis.

 Time (sec) Time, column 15 Time, column 210 Time, column 315 Time, column 420 Distance (ft) Distance, column 111 Distance, column 222 Distance, column 333 Distance, column 444
1. What is Beth’s rate of travel?

Rate is distance divided by time.

2.2 feet per second

2. 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.

• Find the number of feet Amy would travel per second.
• $\frac{75\ \text{feet}}{30\ \text{seconds}}=2.5 \frac{\text{feet}}{\text{second}}$
