Two boats leave a port at the same time one going north and the other traveling south.
The northbound boat travels 18 mph faster than the southbound boat.
If the southbound boat is traveling at 46 mph, how long will it be before they are 1650 miles apart ?
~~~~~~~~~~~~~~~~~~~~

1.  Northbound boat rate = 46 + 18 = 64 mph.


2.  The problem asks at which time "t" it will happen

    46t + 64t = 1650,


    and the answer is: at t = 1650%2F%2846%2B64%29 = 1650%2F110 = 15 hours.

Solved.
