Kelli and her husband Reese are on their way to Disney World. Their plane is going to be traveling 190 miles west at 100 miles per hour. What is the velocity of their plane? Its science it just it didn't let me put it as science

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.
