Question 906672
Think of this as Anne standing still and Pat
walking at the sum of their speeds.
Let {{{ t }}} = the time in hrs it takes
for them to meet
{{{ 15 = ( 3 + 2 )*t }}}
{{{ t = 15/5 }}}
{{{ t = 3 }}}
They will meet in 3 hrs
---------------------
check:
Anne's equation:
{{{ d[1] = 3t }}}
{{{ d[1] = 3*3 }}}
{{{ d[1] = 9 }}}
-------------
Pat's equation:
{{{ d[2] = 2t }}}
{{{ d[2] = 2*3 }}}
{{{ d[2] = 6 }}}
{{{ d[1] + d[2] = 9 + 6 }}}
{{{ d[1] + d[2] = 15 }}}
OK
