So,
Molly runs two-thirds of a mile in 8 minutes.
[tex] \frac{2}{3} = 8[/tex]
Multiply both sides of the equation by the reciprocal.
[tex] \frac{2}{3} * \frac{3}{2} = \frac{8}{1} * \frac{3}{2} [/tex]
[tex]1\ mile\ = \frac{8}{3} \ min.\ or\ 2 \frac{2}{3}\ min.\ or\ 2.666...\ min.\ or\ 2\ min.\ 40\ secs.[/tex]
