Two planes take off at the same time from an airport. The first plane is flying at 240 miles per hour on a bearing of S 45.0° E. The second plane is flying in the direction S 45.0°W at 290 miles per hour. What is the bearing of the second plane from the first after 5 hours? (Round your answer to one decimal place.)

The first plane ends up at (169.7,-169.7)
The other plane ends up at (-205.1,-205.1)
So, relative to the first, the second plane is at
(-374.8,-35.4)
arctan(-35.4/-374.8) = 185.4°, or W5.4°S
