Donna hikes 1/3 mile every 1/6 hour. draw a model to show how many miles she hikes in one hour and how much time it takes her to hike 1 mile.

Part A) 2 miles

Part B) 1/2 hour

Part C) The model in the attached figure

Step-by-step explanation:

Let

x -----> the number of miles

y -----> the time in hours

we know that

so

-----> equation A

Part A) Find out how many miles she hikes in one hour

so

For y=1 hour

substitute in the equation A and solve for x

Part B) Find out how much time it takes her to hike 1 mile

so

For x=1 mile

substitute in the equation A and solve for y

Part C) Draw a model

The double number line in the attached figure

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

a and c
