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

9 minutes per mile.

Step-by-step explanation:

3 miles takes 27 minutes, so:

1 mile takes 27/3 = 9 minutes.

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.

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
