A boat leaves a dock at 2:00 P. M. and travels due south at a speed of 10 km/h. Another boat has been heading due east at 20 km/h and reaches the same dock at 3:00 P. M. How many minutes past 2:00 P. M. were the boats closest together?

it's both, now can you answer my most recent question?

all it means is function 3

explanation:

previous steps have made pa≅ pb ≅ st ≅ su. setting the compass width to ab allows you to make tu the same length. then δstu ≅ δpab by the sss congruence postulate, and ∠p ≅ ∠s by the reason cpctc.
