Question 1158412
Add their rates of travel
Let {{{ s }}} = the speed of the slower group in mi/hr
{{{ 1.5s }}} = the speed of the faster group in mi/hr
---------------------------
{{{ 1300 = ( s + 1.5s )*200 }}}
{{{ 6.5 = 2.5s }}}
{{{ s = 2.6 }}}
and
{{{ 1.5s = 1.5*2.6 }}}
{{{ 1.5s = 3.9 }}}
-----------------------
Their speeds are 2.6 mi/hr and 3.9 mi/hr
-----------------------
check:
{{{ 1300 = ( s + 1.5s )*200 }}}
{{{ 1300 = ( 2.6 + 3.9 )*200 }}}
{{{ 1300 = 6.5*200 }}}
{{{ 1300 = 1300 }}}
OK
