Two cruise ships left the same port. After two hours, Ship A is 30 miles west and 18 miles north of the port and Ship B is 10 miles west and 27 miles south of the port. If there is a tug boat located one-fifth of the way from Ship A to Ship B, find the location of the tug boat relative to the port.
Draw a cartesian coordinate system of the given points
A -30, 18 and B -10,-27 find 1/5th of the way from A to B
x from -30 to -10 is a change of 20 1/5 *20 added to -30 = -26
y from 18 to -27 is a change of -45 1/5 * -45 added to 18 = 9
-26, 9 is 26 miles west of port and 9 miles north of port
