From A to B a private plane flies 1.5 hours at 110 mph on a bearing of 369. It turns at point B and continues another 1.9 hours at the same speed, but on a bearing of 126° to point C. (Round each answer to three decimal places). At the end of this time, how far(in miles) is the plane from its starting point?

On what bearing (from due north) is the plane from its original location?
