Question 175381
Sheely's distance:
{{{2*(1/4) = 2/4}}}
{{{2/4 = 1/2}}}mi
---------------
Lynne's distance:
{{{3*(1/8) = 3/8}}}mi
Now show both distances as eighth miles so 
you can compare them
Sheely:
{{{1/2 = 4/8}}}mi
Lynne:
{{{3/8}}}mi
Difference:
{{{4/8 - 3/8 = 1/8}}}
Sheely ran {{{1/8}}} mi farther
