A person takes a trip, driving with a constant velocity of 94.56 km/h, for 45.57 km, how much time in hours, is spent on the trip?

What is the most useful equation for electric power?

Assume that a person skiing high in the mountains at an altitude of h = 15100 ft takes in the same volume of air with each breath as she does while walking at sea level. determine the ratio of the mass of oxygen inhaled for each breath at this high altitude compared to that at sea level. assume that the air composition (i.e. % of air that is oxygen) is the same at sea level as it is at 15100 ft.
