Answer 1

D=rt       120=40mph*3hours

Answer 2

Answer:

This proportion is valid to represent the problem $\frac{miles}{hours} = \frac{40}{1}=\frac{120}{3}$

Step-by-step explanation:

A proportion is simply a statement that two ratios are equal.

With the data provided for the problem you can say that $\frac{40}{1}=\frac{120}{3}$ this proportion is read as "forty miles is to 1 hour as one hundred twenty miles is to three hours."
