Two ships leave port at the same time, Ship X is heading due north and Ship Y is heading due east. Eleven hours later they are 550 miles apart. If the Ship X had
travels 440 miles from the port, how many miles will Ship Y travel?

330 miles

Step-by-step explanation:

You can solve it using the Pythagoras theorem.

x=Distance from the port to ship Y

550²=440² + x²

x²=550²-440²

x²=302,500-193,600

x²=108,900

x=330
