At the start of a trip, a driver adjusts the absolute pressure in her tires to be 2.85E+5 Pa when the outdoor temperature is 280 K. At the end of the trip she measures the pressure to be 3.01E+5 Pa. Ignoring the expansion of the tires, find the air temperature (in K) inside the tires at the end of the trip. Do not enter unit.
