Question 1094891
Let {{{ s }}} = the speed of the snake in ft/sec
{{{ s + 2 }}} = your speed in ft/sec
------------------------------------
Since you are going in opposite directions, you
can think of this as the snake standing still
and you running at the sum of your speeds
{{{ 2500 = ( s + s + 2 )*60 }}}
{{{ 2500 = 120s + 120 }}}
{{{ 120s = 2380 }}}
{{{ s = 19.8333 }}} ft
also:
{{{ .8333*12 = 10 }}} in
----------------------
{{{ s + 2 = 21.8333 }}}
----------------------
The snake's speed is 19 ft 10 in per sec
Your speed is 21 ft 10 in per sec
---------------------------------------
check:
(1) {{{ d[1] = s*t }}}
(1) {{{ d[1] = 19.8333*60 }}}
(1) {{{ d[1] = 1190 }}}
and
(2) {{{ d[2] = ( s + 2 )*t }}}
(2) {{{ d[2] = 21.8333*60 }}}
(2) {{{ d[2] = 1310 }}}
and
{{{ d[1] + d[2] = 1190 + 1310 }}}
{{{ d[1] + d[2] = 2500 }}} ft
as it should
OK
