Answer:
Suzie walks faster by 0.27 miles per hour.
Step-by-step explanation:
Addie walked miles in 45 minutes and Suzie covered
miles in
of an hour.
So, Addie walked 2.5 miles in 45 minutes i.e. hours.
Therefore, the walking speed of Addie is miles per hour.
Again, Suzie covered i.e. 2.4 miles in
i.e. 0.67 hours.
So, the walking speed of Suzie is miles per hour.
Hence, Suzie walks faster by (3.6 - 3.33) = 0.27 miles per hour. (Answer)
Answer:
The graph in the attached figure
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or
In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin
Remember that
The unit rate of change is the same as the slope
so
In this problem
The linear equation is equal to
To graph the line we need two points
we have (0,0) because the line passes through the origin
Determine other point
assume a value of x and calculate the value of y
For x=8
The other point is (8,3)
Plot the points and join them to draw the line
