# The bus Benito takes to work averages 15 miles per hour in rush-hour traffic. In all he has about $$7\frac{1}{2}$$ miles to travel. About how many hours does it take him to get to work?

$$\frac{1}{2}$$

Explanation

Use the formula t = d ÷ r. Put $$7\frac{1}{2}$$ in place of d and put 15 in place of r.
$$t=7\frac{1}{2} \div 15$$
$$t=\frac{15}{2} \div \frac{15}{1}$$
$$t=\frac{15}{2} \times \frac{1}{15} = \frac{1}{2} \times \frac{1}{1}= \frac{1}{2}$$
It took Benito about $$\frac{1}{2}$$ hour to get to work.
