for each revolution of the tire , the bicycle travels ... 2.5 π ft

revs = 5280 / (2 π)

n = numbrs of revolutions

Circumference of a tires:

C = d π = 2.5 π = 2.5 ∙ π = 2.5 ∙ 3.14159 = 7.853975 ft

n = 1 mile / C

n = 5280 / 7.853975 = 672.2710474633 revolutions


n = 672.3 revolutions

rounded to the nearest tenth.
