Question

Pilar and Tom race home from the park. The graph shows how far each person is from home after a given amount of time.

Answer 1

Each point in the graph has two coordinates, X and Y, X is the horizontal position (minutes) and Y is the vertical (distance from home). We can see in the plot that both Pilar and Tom started at (0;9.5), however, Pilar arrives at the house (Y=0) after 7 minutes, and Tom after seemingly 9.5 minutes.
So Pilar's Speed (now P) is:$P=\frac{9.5}{7}= 1.357 miles /second (aprox)$
And Tom's Speed (now T) is:$P=\frac{9.5}{9.5}= 1 miles /second$
Som Pilar's rate is higher than Tom's. S > T
