Tim decides that he is going to walk to a friend's house, which is 1 mile away from his house. He can walk at a pace of 2/3 miles in 16 minutes. At this rate, how long will it take him to get to his friends house?

If Tim can walk 2/3 miles in 16 minutes, then the time it will take him to walk 1 mile is (16 minutes)/(2/3 miles) = 24 minutes. Answer: \boxed{24}.
