Question 820544
Let {{{ t[1] }}} = time spent paddling
Let {{{ t[2] }}} = time spent drifting
-----------------
{{{ 24 = 6t[1] + 2t[2] }}}
{{{ 3t[1] + t[2] = 12 }}}
{{{ t[1] = (-1/3)*t[2] + 4 }}}
-----------------------
If {{{ t[2] = 6 }}},
{{{ t[1] = (-1/3)*6 + 4 }}}
{{{ t[1] = -2 + 4 }}}
{{{ t[1] = 2 }}}
