**Steve**, Tuesday, November 6, 2012 at 2:52pmLabel the observers A and B, with point C on the line AB, directly below the balloon, at point D.

If x is the distance CB, then since AC+CB=3,

(3-x)tan28° = xtan31°

x = 1.4 miles.

Now, you want the distance DB, which is

x/DB = cos31°

DB = x/cos31° = 1.4/.857 = 1.63 miles
