Question 1111959
Let {{{ s }}} = the speed of the slower jet in mi/hr
{{{ s + 74 }}} = the speed of the faster jet in mi/hr
-----------------------------------------------
You can think of this as one of the jets travelling at
the sum of their speeds and the other standing still
---------------------------------------------------
{{{ 12224 = ( s + s + 74 )*8 }}}
{{{ 12224 = 16s + 592 }}}
{{{ 16s = 11632 }}}
{{{ s = 727 }}}
and
{{{ s + 74 = 801 }}}
--------------------
Faster jet: 801 mi/hr
Slower jet: 727 mi/hr
---------------------------
check:
{{{ d[1] = 727*8 }}}
{{{ d[1] = 5816 }}}
and
{{{ d[2] = 801*8 }}}
{{{ d[2] = 6408 }}}
--------------------------
{{{ d[1] + d[2] = 5816 + 6408 }}}
{{{ d[1] + d[2] = 12224 }}}
OK
