mio is on the running team. she runs 4 laps in 6 minutes. use the table in your student edition if it helps with your thinking.

1. how many laps per minute does mio run?
2. how many minutes per lap does mio run?
3. at this rate, how many laps can mio run in 15 minutes?
4. at this rate, how long will it take for her to run 15 laps?

Explanation:

1. How many laps per minute does Mio run?

Step1: Identify the rate formula

To find laps per minute, we use the formula: Laps per minute = Number of laps / Time in minutes.

Step2: Substitute the values

Mio runs 4 laps in 6 minutes. So, laps per minute = $\frac{4}{6}=\frac{2}{3}$ laps per minute.

Step1: Identify the rate formula

To find minutes per lap, we use the formula: Minutes per lap = Time in minutes / Number of laps.

Step2: Substitute the values

Mio runs 4 laps in 6 minutes. So, minutes per lap = $\frac{6}{4}=\frac{3}{2} = 1.5$ minutes per lap.

Step1: Recall the laps per minute rate

From part 1, Mio runs $\frac{2}{3}$ laps per minute.

Step2: Multiply by time

To find the number of laps in 15 minutes, we multiply the laps per minute rate by 15 minutes. So, number of laps = $\frac{2}{3}\times15 = 10$ laps.

Answer:

$\frac{2}{3}$ laps per minute

2. How many minutes per lap does Mio run?
