Assuming a typical efficiency for energy use by the body, how many slices of pizza must you eat to walk for 3.0h at a speed of 5.0 km/h? assume that your mass is 68 kg, metabolic power of 68 kg individual walking at 5 km/h is 380 w , and the energy content of slice of pizza is 1260 kj. number of slices of pizza=

n = 3.26

Explanation:

given,

human need 380 W of power to walking 5 Km/hr

human body 380 J of energy per second for walking 5 Km/h

speed of human 5 x 0.278 = 1.39 m/s  

for walking 1.39 m energy required = 380 J

distance traveled in 3 hours of walking

d = 1.39 x 3 x 3600

d = 15012 m

energy needed

E = 4,104,000 J

now,

one pizza slice give 1260000 J pf energy

slice of pizza

n = 3.26

colorectal cancer may also develop from areas of abnormal cells in the lining of the colon or rectum. this area of abnormal cells is called dysplasia and is more commonly seen in people with certain inflammatory diseases of the bowel such as crohn's disease or ulcerative colitis.
