1) The distance between r and 0 is 3 times the distance between m and 0.
(2) 12 is halfway between m and r.

I must admit: Charles is correct

Thus is funny. I originally answered with m = 6 and r = 18.  However i then saw the answers that discussed 2 possibilities.

Charles, with all due respect to you, Distance is an absolute and therefore a positive number. the distance between 0 and - 36 is +36, Not -36 as you postulate.  the question does not say r= 3m; it uses the the concept of distance. this means | r - 0 | =
| 3M - 0 |. I see that you are a college professor but I believe you have this wrong.

Sir, with due respect, you seem to have assumed that M and R are both positive. That is not the case. M could be -12 and R could be 36 while still satisfying the conditions in 1. and 2.
