Question 1157210
Let {{{ d }}} = the distance between Seattle & the wilderness
Let {{{ t }}} = the time for the 1st trip in hrs
{{{ d = 132t }}}
{{{ d = 231*( 6 - t ) }}}
{{{ 132t = 231*( 6 - t ) }}}
{{{ 132t = 1386 - 231t }}}
{{{ 363t = 1386 }}}
{{{ t = 3.8182 }}}
and
{{{ d = 132t }}}
{{{ d = 132*3.8182 }}}
{{{ d = 504 }}}
Seattle is 504 mi from wilderness
----------------------
check:
{{{ d = 231*( 6 - t ) }}}
{{{ 504 = 231*( 6 - t ) }}}
{{{ 504 = 231*( 6 - 3.8182 ) }}}
{{{ 504 = 231*2.18182 }}}
{{{ 504 = 503.996 }}}
error due to rounding off
OK
