Answer:
3 minutes per lap; 15 push-ups per day
Explanation:
To find the unit rate, you need to divide minutes by laps.
42.75 minutes / 14.25 laps
You can put this into your calculator and divide, or you can simplify the fraction. Either way, you get 3 minutes per lap.
So, your answer for this problem is 3 minutes per lap.
For the other question, it's the same thing; just divide the total push-ups by days, instead of minutes by laps.
So we can divide using the numbers in the first row: 30 total push-ups / 2 days.
Divide this in your calculator, or mentally, and you get 15 push-ups per day.
