AI Thread Summary
To calculate miles per gallon (MPG), divide the total miles traveled by the gallons used. In this case, for a car that travels 260 miles using 8.2 gallons, the calculation is 260 divided by 8.2. This results in approximately 31.707 MPG when rounded to three decimal places. The discussion highlights the simplicity of the calculation process, with one participant expressing surprise at how straightforward it is. Understanding this formula can help in assessing vehicle fuel efficiency effectively.

Let x be the amount of miles per gallon. Then 8.2 * x = 260. Can you solve for x?

No I don't know how... it's been years.

8.2 * x = 260

Divide both sides by 8.2:

x = 260/8.2 is 31.707 to 3 decimal places.

Do you understand?
 
WHAAAT it's that simple? Oh God. Thanks for your help and patience.
 
Seemingly by some mathematical coincidence, a hexagon of sides 2,2,7,7, 11, and 11 can be inscribed in a circle of radius 7. The other day I saw a math problem on line, which they said came from a Polish Olympiad, where you compute the length x of the 3rd side which is the same as the radius, so that the sides of length 2,x, and 11 are inscribed on the arc of a semi-circle. The law of cosines applied twice gives the answer for x of exactly 7, but the arithmetic is so complex that the...
