A boat leaves a dock at noon and heads west at a speed of 25 km/h. Another boat heads north at 20 km/h and reaches the same dock at 1:00pm. When were the boats closest to each other?


this is a hard one

How far have you gotten? You've had enough other, similar exercises done for you that I'm sure you've at least been able to draw a triangle. How have you labelled it? What equation have you developed? What are you thoughts? Where are you stuck?

Thank you.

Or read the reply to another instance of this exact same exercise, posted only one minute after your post.

What a curious coincidence. :roll:
