Ryan runs 2 laps around the track in 4 minutes. A. Complete the double number line. B. If Ryan continues to run at the same pace, how many laps does he run in 10 minutes? C. If Ryan continues to run at the same pace, how many minutes does it take him to run 7 laps?



Answer :

Part A: Completing the number line.

Divide the number of minutes by the number of lap to get the rate.

[tex]4\text{ min}\div2\text{ lap}=2\text{ min per lap}[/tex]

Using the information, we therefore have the number line.

Part B: How many laps in 10 minutes.

Based on the number line that in the previous part, in 10 mins, Ryan would have ran a total of 5 laps.

Part C: How many minutes in 7 laps.

If we continue the line past 6, then on the 7th lap, Ryan would have ran for 14 mins.
