Question 910205
Think of one car as standing still and
the other traveling at the sum of
their speeds
--------------------
{{{ 528 = ( 80 + 96 )*t }}}
{{{ t = 528 / 176 }}}
{{{ t = 3 }}}
They will be 528 km apart in 3 hrs
----------------
check:
{{{ d[1] = 80t }}}
{{{ d[1] = 80*3 }}}
{{{ d[1] = 240 }}}
and
{{{ d[2] = 96t }}}
{{{ d[2] = 96*3 }}}
{{{ d[2] = 288 }}}
----------------
{{{ d[1] + d[2] = 240 + 288 }}}
{{{ d[1] + d[2] = 528 }}}
OK
