You can enter units that are combinations of units with prefixes. However, you must maintain the same unit system given in the problem. For example, this question uses the SI unit system, Therefore an answer in U. S customary units, such as miles per hour would not be accepted as correct. A car traveling with constant speed travels 150 km in 7200 s.
What is the speed of the car?
Express the speed to two significant figures and include the appropriate units.

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.
