Answer 1

1596 miles

Explanation:

A suitable proportion can be ...

`\frac{\text{miles}}{\text{hours}}=\frac{M}{14\text{ h}}=\frac{342\text{ mi}}{3\text{ h}}\\\\M=(14\cdot 342)/(3)\text{ mi}=1596\text{ mi}`

We solved it by multiplying both sides by 14 hours. The units of hours cancel, leaving units of miles.

Michelle's car can travel 1596 miles in 14 hours.
