A circular jogging path forms the edge of a circular lake that has a diameter of 2 miles. Johanna walked once around the track at the average rate of 3 miles per hour. If t represents the number of hours it took Johanna to walk completely around the lake, which of the following is a correct statement?
The answer was 2<t<2.5.
I divided the distance by the rate to get the time. Since the distance in this case should be 2pi.... time should be 2pi/3. Is this right?
