An airplane is flying on a heading of 115° with a constant velocity of 675 mph. How far south will it
travel in 2 hours if it continues to maintain its velocity?

A. 290 miles
B. 570 miles
C. 310 miles
D. 610 miles

• Trigonometry -

a distance d at 115° will travel d sin 25° south.

So, in 2 hours, having gone 1350 miles, it will have gone 1350 sin 25° = 570 miles south.
