Austin takes 1 minute and 45 seconds to run three-quarters of a circular track. His rate of motion is pi /____ radians per second.
I can't figure out how to convert this to the answer format they want.  I know that 3π/2 is the position on the circle and I converted the time to 105 seconds.  I don't know what to do next.
