$A, S, M$ and $D$ are functions of $x$ and $y$, and they are defined as follows: $A(x, y) = x + y$ $S(x, y) = x - y$ $M(x, y) = xy$ $D(x, y) = x/y$, where $y \neq 0$. A man travels three-fifths of distance $AB$ at a speed of $3a$, and the remaining at a speed of $2b$. If he goes from $B$ to $A$ and back at a speed of $5c$ in the same time, then: $1/a+1/b=1/c$ $a+b=c$ $1/a + 1/b=2/c$ None of these
