Areilla jogs 3 1/8 miles in 5/8 of an hour. express her speed as a unit rate in miles per hour.

5 miles per 1 hour

Step-by-step explanation:

A unit rate is a comparison of a value per 1. This means the denominator of the fraction is 1.

To find it, write a ratio between miles and hours as 3 1/8 miles  per 5/8 hours. To make it a unit rate, divide the two values.

This means the unit rate is 5 miles/ 1 hour.

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl

what is the question?
