                SPEEDS          TIMES            DISTANCE

GOING TO          160           d/160              d

RETURN            120           d/120              d

TOTAL                            7
</pre>
Solve for d, in {{{d/160+d/120=7}}}.


{{{LCD=3*4*4*10}}}

-

{{{3*4*4*10(d/160+d/120)=3*4*4*10*7}}}

{{{3d+4d=480*7}}}

{{{7d=480*7}}}

{{{highlight(d=480)}}}
