The hike to the peak of Mount Hallasan on Jeju Island requires a climb of 1950 m of vertical elevation. Suppose a person with a mass of 68.0 kg is 26.0 % efficent at converting food energy to useable energy.   How many food calories would the person to eat in order to fuel his/her climb to the top of Mount Hallasan? Ignore any energy lost due to sideways motion (consider only energy lost due to the elevation change)
