Rick is taking a 1-mile ride on his bicycle. For each rotation of his tire, he travels 72 inches. How many rotations will his tire make during the 1-mile trip?

73 rotations
83 rotations
780 rotations
880 rotations

1 answer

To find the number of rotations, we need to convert the distance in miles to inches. Since there are 5280 feet in a mile and 12 inches in a foot, 1 mile is equal to 5280*12 = 63360 inches.
Since one rotation of the tire is equal to 72 inches, the number of rotations will be 63360/72 = <<63360/72=880>>880 rotations. Answer: \boxed{880}.
