Question 1093353
Let the speed of Seattle plane = {{{ s }}} mi/hr
{{{ s - 28 }}} = speed of Boston flight
Let {{{ d }}} = distance in miles to Seattle
{{{ 3124 - d }}} = distance to Boston
----------------------------------------
(1) {{{ d = s*5.5 }}}
(2) {{{ 3124 - d = ( s - 28 )*2 }}}
-------------------------------------
Solve for {{{ s }}}and {{{ s-28 }}}, then check answer by plugging
{{{ s }}} back in and solving for {{{ d }}}
