The basal metabolic rate (BMR) is the minimum energy intake required to maintain a body that is awake and at rest. While the rate varies with age, gender, health, and body mass, a reasonable value is 1600 Cal per day. Walking can require 2.5 times the BMR, and exertion in work or sports can require 7 times the BMR. Using this information, calculate the energy expended by someone walking at a speed of 3.0 mph and determine how far she could walk with the energy from a quarter-pound hamburger (125 g) that has a food value of 3.6 Cal/g.
