You can put this solution on YOUR website! A ship leaves port at 12:00 pm (noon) and sails east at 10 miles per hour. Another leaves the same port at 1:00 pm and sails north at 20 miles per hour. At what time are the ships 50 miles apart?
====================
t = 0 at 1 PM
Distance from port:
Eastbound = 10t + 10
Northbound = 20t
---
(5t + 12)*(t - 2) = 0
t = 2 hours (Ignore the negative solution)
--> 3 PM
