Answer:
Pool A.
Step-by-step explanation:
This can be solved through ratios. You would write it as
So,
for the first one, and
for the second. You might want to use a calculator for that part, but you could also change the gallons to cups, which gives you a much better number of 10.515. So,
, and
So, pool A is at a faster rate. If you want it in gallons per minute, it's by 0.01 (with the 1 repeating) gallons per minute. By cups, it's 0.17525 cups per minute.
(The reason I did not do this by cross multiplying and dividing ratios is because it gives you the exact same answer if you are finding it per one, as I am here with per one minute. You can do it this way, it just wastes a bit of time.)
The answer is C 20*4.8=96 and 30*3.2=96 so in other ways the are the only one that give the same number.
Answer:
The slope is 6/5. So Marcy hiked 6 miles every 5 hours. The unit rate is 1.2 miles every 1 hour.
