Carlos likes to go hiking on the weekends with his dog. He travels 3 miles in 45 minutes and hits a picnic area to take a break. He then continues his hike. When he reaches the end of the hike, he figures out that he traveled a total of 9 miles in 2 hours and 15 minutes. What was Carlos’ rate of walking? please help quickly!
