To find out how many minutes Derek took to ride his bike to the park, we first need to calculate how long it took him to ride 3 miles at a speed of 9 mph.
Time = Distance / Speed
Time = 3 miles / 9 mph
Time = 1/3 hour

1/3 hour * 60 minutes = 20 minutes
Therefore, Derek took 20 minutes to ride his bike to the park.
