Two planes take off at the same time from an airport. The first plane is flying at 266 miles per hour on a course of $150.0^{\circ }$. The second plane is flying in the direction of $175.0^{\circ }$ at 233 miles per hour. Assuming there are no wind currents blowing, how far apart are they after 3 hours? Round your answer to the nearest mile. miles
