Homework Help: Trig.

Posted by Sam on Monday, December 21, 2009 at 9:43pm.

An airplane flying at 600 miles per hour has a bearing of 52 degrees. After flying for 1.5 hours, how far north and how far east will the plane have traveled from point of departure?

(I'm not sure how to convert miles into degrees or if that's even the right thing to do)

The bearing of &theta=52 degrees is measured from the north.

At 600 miles per hour for 1.5 hours, the plane would be D=600*1.5=900 miles from the point of departure.

The northing would be D cosθ and the easting would be D sinθ.
