You can put this solution on YOUR website! Use the law of sines
A/sinA = B/sin B = C/sin C
Angle F has 91 degrees
sin 91/18.3=.0546
Solving for the other two sides, BF is 14.23 miles; AF is 11.27 miles. It is 2.96 miles closer from A, and at 150 mph it is 0.0197 hours, or 71 seconds or a minute and 11 seconds.
