Question 944267
Think of this as one cr standing still and the
other moving at the sum of their speeds
Let {{{ s}}} = the speed of the slower car in km/hr
{{{ s + 14 }}} = the speed of the faster car in km/hr
---------------------
{{{ 600 = ( s + s + 14 )*3 }}}
{{{ 600 = 6s + 42 }}}
{{{ 300 = 3s + 21 }}}
{{{ 3s = 279 }}}
{{{ s = 93 }}}
{{{ s + 14 = 107 }}}
The faster car's speed is 107 km/hr
check:
{{{ 600 = ( s + s + 14 )*3 }}}
{{{ 600 = 200*3 }}}
{{{ 600 = 600 }}}
OK
