Derrrick lives 3 mies from the park. He rode his bike to the park at an average speed of 9 miles per hour. How many minutes did it take Derrick to ride his bike to the park?

Lets make it in ratio:
3 miles:x
9 miles:1 hour or simply 60 min

9 miles:60 min
Simplify the ratio
3 miles:20 min

Therefore, 3 miles would take him about 20 minutes. Hope this helps =)
