Question 277004
Two different online webpages showed about 2600 miles between LA and Boston
by air.  If we did not know and use d for this distance, then


Time  for Boston to LA,  {{{d/525}}}

Time for LA to Boston, {{{d/600}}}

and difference was given,  {{{d/525-d/600=2/3}}}


{{{d(1/525-1/600)=2/3}}}

{{{d(1/175-1/200)=2}}}

{{{d(1/1400)=2}}}

{{{highlight(highlight(d=2800))}}}  MAYBE.
