I bet your kids are getting excited about Spring Break. I saw this math problem and it made me think of vacationing on the high seas!

On a certain day, the visibility at sea is 5 km.

Boats A and B are 200 m apart and travelling in opposite directions, each at a diļ¬€erent, constant speed. The two boats are in sight of one another for 15 minutes.

If boat A is travelling at a constant speed of 8 km/h, how fast is boat B travelling, in km/h?

You could probably get some cupcakes and pretend they are boats while you think about this one. And then you could eat the boats.
