Question 897951
Start a stopwatch when the groom leaves
Let {{{ d }}} = the distance in miles  he 
has to travel to catch bride
Let {{{ t }}} = his time in hours to catch bride
---------------------------------------
Bride's equation:
{{{ d - 125 = 65t }}}
Groom's equation:
{{{ d = 80t }}}
--------------
By substitution:
{{{ 80t - 125 = 65t }}}
{{{ 15t = 125 }}}
{{{ t = 8.333 }}} hrs
{{{ .333*60 = 20 }}} min
He will catch her in 8 hrs 20 min
----------
check:
{{{ d = 80t }}}
{{{ d = 80*8.333 }}}
{{{ d = 666.666 }}}
and
{{{ d - 125 = 65t }}}
{{{ d = 65t + 125 }}}
{{{ d = 65*8.333 + 125 }}}
{{{ d = 541.6645 + 125 }}}
{{{ d = 666.6645 }}}
close enough
