Mathematical Puzzles of the Month Help please?
The front wheels of a tractor with a diameter of 2 meters, the rear wheels have a diameter of 3 feet. If the tractor moves a mile, the number of rotations will be a complete front wheel to the rear wheel. Here is the hard part. I need step by step instructions on how to resolve not only the answer.
feet can be used as units. 1 mile = 5280 meters of perimeter of the front feet = 6.28 * 2 = circumference pi = back = 9425 * 3 laps before 5280/6.28 = 840.76 rotation = 841 = Back 5280/9.425 = 560.21 = 560 = difference 840.76-560.21 = 280.55 = 281
