Question 946633
Let {{{ t }}} = minutes that Raoul travels
{{{ 6t }}} = time in minutes 
------------
{{{  t + 6t = 63 }}}
{{{ 7t = 63 }}}
{{{ t = 9 }}}
{{{ 6t = 54 }}}
Hanna travels for 54 min
-----------------------
A pie chart would work
Make 2 slices:
{{{ ( 9/63 )*360 }}} degrees
for Raoul's time
{{{ ( 54/63 ) *360 }}} degrees
for Hannah's time
