-What is the linear velocity of the wheels in inches per minute?
A) about 84,820.6 in/min
B) about 84,821.8 in/min
C) about 84,823.0 in/min
D) about 84,824.8 in/min

Quizplus · Accepted Answer

The linear velocity $v$ of the wheels can be calculated using the formula $v = 2\pi r \times \text{RPM}$, where $r$ is the radius of the wheels and \text{RPM} is the revolutions per minute. Substituting the given values, $v = 2 \times \pi \times 29 \times 250 = 45,500\pi \approx 84,823.0$ inches per minute.
