If you run a marathon of 26 1/5 miles in a time of 5 4/5 how far do you run in 1 hourpls

First let's make both the miles and the hours ran improper fractions:

So, to find our miles per hour, we have to divide the miles by the hours to get:

8121 because

130,000 divided by 16 is 8121

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
