 Math Central Quandaries & Queries
 Question from Karabo, a student: a boat sails 30 km due east from a harbour. Then it sails 40 km due north. How far is it from the harbour?

Draw a diagram.

Can you see how to find the distance from the harbour $H$ to the final position of the boat $F.$ If not then maybe ask Pythagoras.
