 ```If a car has wheels with a diameter of three feet. About how many miles per hour is the car going, if the wheels are turning at about 600 times per minute?```
 ```biga626 -- The answer is approximately 64.26 miles per hour. The formula for solving the problem is found at this website: Math Forum http://mathforum.org/library/drmath/view/60367.html The formula described there for this problem is: (minutes in an hour) X (revolutions per minute) X (wheel diameter in inches) X (pi) DIVIDED BY (feet in a mile) times (inches in a foot) = (speed in miles per hour) Using the numbers you have stated, the problem then would be: 60 X 600 X 36 X 3.1416 DIVIDED BY 5280 X 12 The answer to that problem, as I stated above, is 64.26 mph Search Strategy: I found the formula with the following Google search: formula diameter wheel speed minute ://www.google.com/search?sourceid=navclient&ie=UTF-8&rls=GGLD,GGLD:2004-01,GGLD:en&q=formula+diameter+wheel+speed+minute I urge you to visit the site linked above to get a fuller understanding of the problem and its solution. Other sites returned as "hits" with the Google search terms I used could also be helpful to you. markj-ga```
