Answer:
25.13 inches per second
Explanation:
The formula for linear velocity is:

Where
is the radius, and
is the period of oscilation.
The radius is:
but because we need the answer in inches per second we need to convert this to inches (1 feet = 12 inches):

and the Period is the time it takes to complete a revolucion:
it takes 2 minutes to complete 1 revolution. Again, since we need the result in inches per second we need to convert the Period to seconds (1 minute = 60 seconds)

substituting our values for the linear velocity:


the linear velocity is 25.13 inches per second
