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
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?
