Answer the questions below. Label all the numbers. Justify your response.<br />
1. In <strong>Michael</strong> <strong>Biking</strong>, what are the two quantities being compared?<br />
Distance in miles and time in hours<br />
2. How far can <strong>Michael</strong> ride in one hour? Two hours? Four hours?<br />
Half <strong>of</strong> 2 hours is 1 hour: half <strong>of</strong> 10 miles is 5 miles<br />
The diagram shows 2 hours aligns with 10 miles<br />
Two times 2 hours is 4 hours: 2 times 10 miles is 20 miles<br />
3. How long will it take <strong>Michael</strong> to ride 15 miles? 25 miles?<br />

4. What are the two rates to represent the diagram?<br />
10 miles 2 hours<br />
and<br />

8. How long it will take <strong>Michael</strong> to ride 12 miles (providing his speed is constant)?<br />
0.2 hour per mile x 12 miles = 2.4 hours<br />
9. How far <strong>Michael</strong> can ride in 6 hours (providing his speed is constant)?<br />
5 miles per hour x 6 hours = 30 miles<br />
