Final answer:
The circumference of Mrs. Lynch's tire is approximately 125.6 inches.
Step-by-step explanation:
To calculate the distance that Mrs. Lynch's tire will travel in one rotation, we need to find the circumference of the tire. The formula for the circumference of a circle is C = 2πr, where C is the circumference and r is the radius of the circle. Given that the radius of Mrs. Lynch's tire is 20 inches, we can substitute that value into the formula to find the circumference.
C = 2*3.14*20 = 125.6 inches
Therefore, Mrs. Lynch's tire will travel approximately 125.6 inches in one rotation.
