The Great Lakes contain the largest amount of fresh water on the surface of the planet. Combined, the five lakes (Superior, Michigan, Huron, Erie, and Ontario) contain 84% of north America's and 21% of the world's fresh water. The amount of water in Lake Superior is 1720 cubic miles more than the amount of water in Lake Michigan. Lake Huron has 330 cubic miles of water less than Lake Michigan. If the total amount of water in the three Lakes is 4930 cubic miles, how much water is in each lake?
+36919 Let's say
Lake Mich = x
Lake Superior is then 1720 + x
Lake Huron is x-330
Theay all ad up to 4930
x + (1720+x) + (x-330) = 4930
x = 1180 = Mic
Super = 1720 + 1180 = 2900
Huron = 1180-330 =850
+48 If ''how much water is in each lake?'' refers only to Lake Superior, Michigan and Huron, this should be the answer.
The question gives us some information on the lakes' sizes which we can use to find the answer.
S-1720=M
S-(1720+330)=S-2050=H
Now we do some basic algebra and find the value of S.
S+(S-1720)+(S-2050)=4930
3S-3770=4930
3S=8700
S=2900
Now we use S' value to find the value of M and H.
2900-1720=1180=M
2900-2050=850=H
Answer: Lake Superior contains 2900 cubic miles of water, Lake Michigan contains 1180 cubic miles of water, and Lake Huron contains 850 cubic miles of water.
