Question

Peter jogs 3 miles in 27 minutes. Find the unit rate in minutes per mile.

Answer 1

Answer:

9 minutes per mile.

Step-by-step explanation:

3 miles takes 27 minutes, so:

1 mile takes 27/3 = 9 minutes.

Answer 2

Answer: 1 mile per 9 minutes or 9 minutes per mile

Step-by-step explanation: "Per mile" means in 1 mile so we can rewrite the given statement using fractions.

To find out what goes in the blank, notice that we have a 1 in the denominator of our second fraction so we want to find a fraction that is equivalent to 27/3 that has a 1 in the denominator.

If we divide the numerator and denominator of 27/3 by 3, we get the equivalent fraction 9/1 or 9 minutes over 1 mile.

So now we have 9 minutes over 1 mile = ___ minutes over 1 mile.

So a 9 must go in the blank.

Therefore, the unit rate for 3 miles in 27 minutes is 1 mile per 9 minutes or 9 miles in 1 minute.
