Question 1017963
{{{ d = r*t }}}
Convert minutes to hrs
{{{ 10/60 = 1/6 }}} hrs
{{{ d = 27*(1/6) }}}
{{{ d = 4.5 }}}
She is 4.5 mi from school
----------------------
Let {{{ t }}} = her time in hrs to get
to school at 40 mi/hr
{{{ d = r*t }}}
{{{ 4.5 = 40*t }}}
{{{ t = 4.5/40 }}}
Convert this back to minutes by 
multiplying by {{{ 60 }}}
{{{ t = 4.5*( 3/2 ) }}}
{{{ t = 13.5/2 }}}
{{{ t = 6.75 }}}
This is 6 min 45 sec time to get
to school at 40 mi/hr
