Question 1116430
{{{ c^2  = a^2 + b^2 }}}
{{{ c^2 = 18^2 + 13^2 }}}
{{{ c^2 = 324 + 169 }}}
{{{ c^2= 493 }}}
{{{ c = sqrt( 493 ) }}}
{{{ c = 22.2036 }}}
The ant is 22.2036 in. from starting point
and it has walked {{{ 18 + 13 }}} = 31 in.
----------------------------------------
The 1st ant walked {{{ 31 - 22.2036 }}} = 
8.7964 in further than the 2nd ant
