Not quite. Did you get a distance of 60 km traveled by boat A and 45 km traveled by boat b? And did you then apply the Pathagorean formula (a2 + b2 = c2)?

I get the distance right for both and then I added them that's how I got 105, but if I do the Pythagorean formula I get 75 km apart, is this the right answer?
