Question 1110187
Let {{{ t }}} = time in hrs to travel downstream
{{{ 1.5t }}} = time in hrs to travel upstream
Let {{{ d }}} = one way distance
Let {{{ s }}} = the speed of the boat in still water
Let {{{ c }}} = the speed of the current
------------------------------------------
Equation for going upstream:
(1) {{{ d = ( s - c )*1.5t }}}
Equation for going downstream:
(2) {{{ d = ( s + c )*t }}}
--------------------------------
{{{ ( s - c )*1.5t = ( s + c )*t }}}
{{{ 1.5*( s - c ) = s + c }}}
{{{ 1.5s - 1.5c = s + c }}}
{{{ .5s = 2.5c }}}
{{{ s/c = 2.5/.5 }}}
{{{ s/c = 5/1 }}}
