Two old RSM students were standing twenty feet apart when they spotted Mrs. Rifkin. If they immediately ran in opposite directions
with speeds of 180 feet per minute and 120 feet per minute respectively, how many minutes would pass before they were 2,420 feet apart?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

There are two answers: 

1.  %282420-20%29%2F%28180%2B120%29 = 2400%2F300 = 8 minutes.

and

2.  %282420%2B2%2A20%29%2F%28180%2B120%29 = 2440%2F300 minutes.

There are TWO solutions, and not only ONE - because the term "ran in opposite directions" does not determine
these directions by the unique way in this context.

There are still TWO different scenarios regarding in what directions they do run.
