A ship sail 12 km due north of a port and then sails 14 km due east.
(a) How far is the ship from the port?
Draw the picture.
You have a right triangle with a north leg of 12 and an east leg of 14
Use Pythagoras to find the hypotenuse:
h^2 = 12^2 + 14^2
h = sqrt(340)
hypotenuse = distance from port = 18.44 km
=================================================
(b) How much farther east will it have sailed when it is 30 km from the port?
Draw the picture.
You have a right triangle with a north leg of 12, an east leg of "x"
and a hypotenuse of 30
----
30^2 = 12^2 + x^2
x^2 = 30^2-12^2
x^2 = 756
x = 27.5 km
------------------------------
It will have sailed 27.5-14 = 13.5 km further east.
=====================================================
