Answer:

  π/10 in/s ≈ 0.314 in/s

Step-by-step explanation:

The circumference of the circle it traverses is given by the formula ...

  C = 2πr

Substituting the given radius, we find the distance traveled in 60 seconds to be ...

  C = 2π(3 in) = 6π in

Then the linear speed is ...

  speed = distance/time = (6π in)/(60 s) = π/10 in/s
