Answer:
31,692 inches
Step-by-step explanation:
The length that Marc travelled with his bike can be calculated by the product between the number of rotations of the tire and the circunference of the tire.
So, calculating the circunference of the tire, we have:
C = pi*diameter = pi*26 = 81.68 inches
If in each rotation of the tire, the length travelled is 81.68, the total length travelled is:
Length = number of rotations * C = 388 * 81.68 = 31,691.84 inches
Rounding to the nearest inch, we have Length = 31,692 inches
