Question 462865
let the no. of miles rode on saturday be "x"
then the number of miles rode on sunday wud be = 9 + (2/3)x

totally he rides = 69 miles
i.e,
saturday + sunday = 69

{{{ x + ( 9 + (2/3)x ) = 69 }}}
{{{ (3x + 2x)/3 = 69 - 9 }}}
{{{ 5x = 60 * 3 }}}
{{{ 5x = 180 }}}
{{{ x = 36 }}}

thus,
on saturday he rides 36 miles 
and on sunday = the remaining of 69 miles, i.e 69-36=33 miles
