When navigating their crafts, ship captains and airplane pilots can often be seen drawing lines on a large map?

A cruise ship is traveling in the Atlantic Ocean at a constant rate of

40 mi/h and is traveling 2 mi east for every 5 mi north. An oil tanker is

350 mi due north of the cruise ship and is traveling 1 mi east for every 1

mi south.

a. How far is each ship from the point at which their paths cross?

b. What rate of speed for the oil tanker would put it on a collision

course with the cruise ship?
