Question 365006
The formula is (distance) = (rate) x (time), or
{{{d = r*t}}}
Juan's rate of walking is
{{{1/2}}} mile / {{{5}}} min = {{{1/10}}} mile / {{{1}}} min
Now use the formula
{{{5/8 = (1/10)*t}}}
Multiply  both sides by {{{10}}}
{{{t = 50/8}}}
{{{t = 6.25}}} min
It takes him 6 1/4 minutes to walk 5/8 of a mile
