To reach his potential, Jack wants to increase his running speed by 2/3 mile/hour. It he increases his speed at the rate of 1/8 mile/hour each month, how long will it take him to reach his potential?
= `\frac{\frac{2}{3}}{\frac{1}{8}}`
= `\frac{2}{3} \times \frac{8}{1}`
= `\frac{16}{3}` month
Thus, Jack will take him 16/3 month to reach his potential.
