Chapter 0, Problem 4PR

(a)

To determine

To find: The Lake Superior is how many times larger than Lake Ontario

Answer to Problem 4PR

The Lake Superior is approximately 4 times larger than Lake Ontario

Explanation of Solution

Given:

  

Area of Lake Superior = $31698m^2$

Area of Lake Huron = $23011m^2$

Area of Lake Michigan = $22316m^2$

Area of Lake Erie = $9922m^2$

Area of Lake Ontario = $7320m^2$

Calculation:

The number of times Lake Superior is larger than Lake Ontario can be calculated as

  $=\frac{\text{Area of Lake Superior}}{\text{Area of Lake Ontario}}=\frac{31695m^2}{7320m^2}=4.3303$

Therefore, the Lake Superior is approximately 4 times larger than Lake Ontario

Conclusion:

Therefore, the Lake Superior is approximately 4 times larger than Lake Ontario

(b)

To determine

To find: The number of milesthe Great Lakes covers altogether

Answer to Problem 4PR

The Great Lakes covers $94567m^2$ altogether

Explanation of Solution

Combined area of great lakes in Square miles can be calculated by adding the area of five lakes.

Thus,

  $\left(31698+23011+22316+9922+7320\right)m^2=94567m^2$

The combined area of 5 great lakes is $94567m^2$

Conclusion:

Therefore, the Great Lakes cover $94567m^2$ altogether
