Question 682923
She bikes 82 1/2 miles in 6 3/4 hours.
The ratio of these numbers is a constant, so you
can multiply both by {{{ 4 }}}
{{{ 4*82 + 4*(1/2) = 328 + 2 }}}
{{{ 328 + 2 = 330 }}}
and
{{{ 4*6 + 4*(3/4) = 24 + 3 }}}
{{{ 24 + 3 = 27 }}}
---------------
This means she bikes {{{ 330 / 27 }}} miles/hr
{{{ 330 / 27 =  12 + 6/27 }}}
{{{ 12 + 6/27 = 12 + 2/9 }}}
She traveled 12 and 2/9 miles in 1 hr
