Question: The average energy E (in kcal) needed for a lizard to walk or run a distance of 1 km has been modeled by the equation

The average energy E (in kcal) needed for a lizard to walk or run a distance of 1 km has been modeled by the equation

E(m, v) = 2.65m0.66 + 3.5m0.75/v

where m is the body mass of the lizard (in grams) and v is its speed (in km/h). Calculate Em(400, 8) and Ev(400, 8) and interpret your answers.
