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.
Walking at this pace would take 20 minutes to complete one mile. While 20 minutes satisfies the minimum daily requirements set forth by the CDC, to reach optimal health, 1 mile is insufficient. To exercise for 300 minutes weekly, you would need to walk slightly over 2 miles at 3 mph.
