Step 1: Since the point moves at the rate of 32pi/9 radians per minute, divide this number by 60 to find the

rate per second.

Step 2: Since there are 2pi radians in one revolution, multiply this number by 7 to find the number of radians

in 7 revolutions.

Step 3: Divide the answer of step 2 by the answer of step 1 to find how may seconds that it will take.
