Question

How many laps can jaden complete in 12 minutes

Answer 1

Answer: 96 laps

Explanation:

We are given a unit rate of 8 laps per one minute. Using this unit rate, we can multiply the given minutes by the laps per minute.

`\displaystyle 12\text{ minutes}* 8 \;\frac{\text{laps}}{\text{minute}}=96\text{ laps }`

This gives us an answer of 96 laps.

Answer 2

96 laps in 12 minutes

144 laps in 18 minutes

Explanation:

We can use the unit rate, which is 8 laps in 1 minute

8 laps/ 1 minute * 12 minutes = 96 laps

8 laps/ 1 minute * 18 minutes = 144 laps

We can use also use ratios to solve the problem.

5 minutes 12 minutes

-------------------- = --------------------

40 laps x laps

Using cross products

5*x = 40 * 12

Divide each side by 5.

x = 40/4 * 12

x = 96 laps

5 minutes 18 minutes

-------------------- = --------------------

40 laps x laps

Using cross products

5*x = 40 * 18

x = 40/5 * 18

x = 144
