The distance the sprinter ran is given in meters and the time is given in seconds. convert meters to kilometers and seconds to hours and divide the distance by the time to calculate the average speed.

The size (radius) of an oxygen molecule is about 2.0 ×10−10m. make a rough estimate of the pressure at which the finite volume of the molecules should cause noticeable deviations from ideal-gas behavior at ordinary temperatures (t= 300k ). assume that deviatons would be noticeable when volume of the gas per molecule equals the volume of the molecule itself.
