Question 1052264
Find time in seconds to cover {{{ 1 + 3 = 4 }}} cm
{{{ 4 / 10 = .4 }}} sec
Now find number of {{{ 4 }}} cm intervals in {{{ 500 }}} cm
{{{ 500/4 = 125 }}}
{{{ 125*.4 = 50 }}} sec
{{{ 50 }}} sec for a pair to get into the arc
--------------------------
[ number of species ] / [ species/sec ] = [ sec ]
{{{ .25*10^6 / (1/50) = .25*50*10^6 }}}
{{{ 12.5*10^6 }}} sec
[ sec ] x [ hrs/secs ] = [ hrs ]
{{{ 12.5*10^6 * (1/3600 ) = 12500*10^3 / 3600 }}}
{{{ 3.472*10^3 = 3,472 }}}
3,472 hrs

Hope I got it!
