NCLEX Exam Prep. Created by the National Council of State Boards of Nursing (NCSBN), the National Council Licensure Examination (NCLEX - PN) is the exam required for all nursing students to pass in order to become a Licensed Vocational Nurse (LVN) in the United States.
The Speed You Walk. Intensity is also a big factor in determining how many calories you'll burn during any given activity. According to that same Harvard Medical School calorie chart, the 155-pound person will burn 149 calories per 30 minutes walking at a 3.5-mph pace -- or roughly a 17-minute mile. If she speeds up, she'll burn more calories. Walking 1 mile at 4 mph -- which should take her 15 minutes -- she will burn 83.5 calories.
The people that normally walk very briskly might normally walk 4mph, which would get you a 15 minute mile, but faster than that is going to be uncommon, unless they walk fast for exercise or race walk (At which point the world record pace at the 20km distance works out to be a pace a bit above six minutes/mile).
