Please, can you help me with the following?
A boat B is found at 40km at at the east of
a boat A. A is moving at 30° east at 20km/h,
B is moving qt 10km/h at 30°west.
After how many hours will the two boats
be the closest to each other?
What will therefore be the position of the
boat B and the boat A?
Thank you
