Question 769829
Let {{{ d }}} = distance in miles that you kayak until
you meet the floats
Let {{{ t }}} = the time in hours until you meet the floats
--------------------
(1) {{{ d = ( 4 - 2 )*t }}}
(1) {{{ d = 2t }}}
-------------------
Equation for the floats:
(2) {{{ 8 - d = 2t }}}
----------------
(1) {{{ t = d/2 }}}
Substitute (1) into (2)
(2) {{{ 8 - d = 2*( d/2 ) }}}
(2) {{{ 8 - d = d }}}
(2) {{{ 2d = 8 }}}
{{{ d = 4 }}}
and
(1) {{{ t = d/2 }}}
(1) {{{ t = 2 }}}
You will meet the floats in 2 hrs
You will be {{{ 8-4 = 4 }}} mi from
the fisherman at that point
