Sarah and three of her friends left her house for a long bike ride on the river bike path. They rode for three hours at 10 miles per hour and then rested for an hour while they ate their lunches. After lunch, they raced each other back to Sarah’s house at 15 miles per hour. Homework Help ✎
Draw a graph that could represent this situation. Place “Time (hours)” on the horizontal axis and “Distance (miles from Sarah’s house)” on the vertical axis.
Describe each part of the graph using the following words: linear, nonlinear, decreasing, increasing, and constant.
Recall the Distance = Rate × Time formula.
Make a table of values and graph the points.
Is there a constant slope?
Does your graph have any ups and downs?
