A plane flies 110 miles per hour for 1 hour on a bearing of 040 degrees. from that point it then turns and flies at the same speed on a bearing of 150 degrees of 1.5 hours. how far is the plane from it’s starting point

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
