Answer:
$2\frac13\text{ miles per hour}$

Explanation:

Given: Distance traveled by Smith =
$\frac23$ mile.

Time taken =
$\frac27$ hour

Unit rate in miles per hour = ( Distance traveled by Smith) ÷ (Time taken)

$=\frac23/\frac27$

$\\\\=\frac23*\frac72\\\\=\frac73\\\\=2\frac13\text{ miles per hour}$

Unit rate =
$2\frac13\text{ miles per hour}$
