It is 5.5 kmkm from your home to the physics lab. As part of your physical fitness program, you could run that distance at 10 km/hkm/h (which uses up energy at the rate of 700 WW), or you could walk it leisurely at 3.0 km/hkm/h (which uses energy at 290 WW). Part A Which choice would burn up more energy
