Slowing Down
The section between hours 0 and 1 is steeper than the section between hours 1 and 3. This means that after a fast start, Harry slowed down.
You can also look at the points on the graph to see how quickly he traveled. In the first hour, he cycled 8 miles. In the next 2 hours, he cycled only 2 miles. No wonder he says, “I’m 5 miles behind where I want to be!” at the 3-hour mark!
How does Harry realize he is 5 miles behind schedule? Use the graph to help you explain why he feels he is 5 miles behind. Explain your answer in two to three sentences.
