PLEASE ANSWER QUICKLY 6-93. THE 5-D PROCESS REVISITED

Use the 5-D Process to set up the following problem. Complete only three trials. Even if you do not yet know the solution, wait for your teacher’s instructions.

The Great Lakes contain the largest amount of freshwater 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 surface 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?

Check the reasonableness of the amounts of water you found for each lake by using estimation strategies: Does the total volume of the three lakes seem reasonable?
