Joey and Connie bike from their houses to go to school. The given graph models Connie’s distance in miles (y) from the school when she bikes x minutes. Joey’s house is 3 miles away from the school. He reaches the school in 18 minutes by biking at a constant speed. Which statement is true?
A. Connie bikes faster than Joey.
B. Joey bikes faster than Connie.
C. The two students bike at the same speed.
D. Connie does not bike at a constant speed. So, you cannot compare their speeds.
Since Joey's house is 3 miles away from the school and he reaches the school in 18 minutes, it means that Joey bikes at a constant speed of 3 miles/18 minutes = 1/6 miles/minute.
Since we don't have information about Connie's speed or the specific distances and times in the graph, we cannot accurately compare their speeds. Therefore, the correct answer is D. Connie does not bike at a constant speed. So, you cannot compare their speeds.
