# A crew of highway workers paved 1/15 miles in 10 minutes.If they work at the same rate ,what portion of mile will they pave in one hour?

$\frac{2}{5}$miles

#### Explanation:

Think of it as a ratio

For every 10 minutes, they pave $\frac{1}{15}$ miles
Therefore, in one hour which is 60 minutes, they will have paved $\frac{1}{15} \times 6$ miles since 60 minutes is $6 \times 10$minutes

$\frac{1}{15} \times 6 = \frac{2}{5}$miles

2/5

#### Explanation:

find the part of mile done in one minute
$\frac{\frac{1}{15}}{\frac{10}{1}}$ = $\left(\frac{1}{15}\right) \cdot \left(\frac{1}{10}\right)$ = $\frac{1}{150}$mile in 1 minute
$\therefore$in 60 min = $\frac{1}{150} \cdot 60$ = $\frac{60}{150}$= $\frac{2}{5}$ of a mile in 1 hr.
