Answer:

See below

Step-by-step explanation:

When you see PER think fractions. Miles PER hour is

[tex] \frac{miles}{hour} [/tex]

We are given miles and told to solve for time. Use your knowledge of fractions to get what you need

The reciprocal of mi/hr would get what we need

[tex]miles \times \frac{hours}{miles} [/tex]

Miles cancels out here. So that means you can do this

[tex] \frac{1hour}{50miles} \times 999.9 \: miles[/tex]

In your calculator. Same with the other rate.
