Question 547814
You can think of 1 hiker as standing still
and the other approaching him at the
sum of their speeds.
Let {{{ s }}} = Alan's speed in mi/hr
{{{ s + .5 }}} = Ben's speed in mi/hr
{{{ 2s + .5 }}} = the sum of their speeds
------------------------------
given:
{{{ 8.2 = ( 2s + .5 )*2 }}}
{{{ 8.2 = 4s + 1 }}}
{{{ 4s = 7.2 }}}
{{{ s = 1.8 }}}
{{{ s + .5 = 2.3 }}}
Alan's speed is 1.8 mi/hr
Ben's speed is 2.3 mi/hr
