Answer:
Step-by-step explanation:
This is a d = rt problem; but since it is linear, then proportions will work too. Set up the proportion with miles on top and hours on the bottom:

Then put the numbers in where they go, keeping in mind that miles goes with miles and hours goes with hours in the ratios, and that our unknown is time (hours):
and cross multiply to solve:
638x = 4466 so
x = 7 hrs
The answer is D and it is the correct answer
Answer:
30
Step-by-step explanation:
If Rodger has 15 cups of punch. There are glasses that have a 1/2 cup capacity. This means he is going to divide a 15 cups into 1/2 cups.
15/1 x 2/1 = 30/1
This means he will have 30 cups to fill.
B. because the slope is negative 5 so it can't be a or d. the y-interept can't be one because it is 11.
