Okay, let's say back in my fleet-footed days (my twenties--when I was also forty pounds lighter! EEK!) I could run 3 miles in 18 minutes. Actually, my fastest time was 17:25--stud! Calculate my miles per hour for running 3 miles in 18 minutes. (Now I'm doing great to run 3 kilometers in 18 minutes!)
