Three friends, Joey, Chandler and Ross meet for breakfast at 9:00 AM at Central Perk every morning. Joey walks, Chandler bikes, and Ross drives. Yesterday all three were exactly on time. Joey left his house at 8:30 AM and walked at a rate of 3 miles per hour. Chandler left his house at 8:15 AM and biked at a rate of 14 mph. Ross left her house at 8:45 AM and drove an average speed of 35 mph. If the person who traveled the farthest live m miles from the restaurants, the what is the value of 2m?
