The distance traveled in a car varies directly as the amount of gasoline used. If a car travels 640 miles and uses 32 gallons of gas, determine the constant of proportionality (miles per gallon).(1 point)

Question

The constant of proportionality is
miles per gallon.

Answer 1

To find the constant of proportionality (miles per gallon), you can use the formula:

\[ \text{Constant of Proportionality} = \frac{\text{Distance traveled}}{\text{Gasoline used}} \]

In this case, the car travels 640 miles and uses 32 gallons of gas. Plugging in these values gives:

\[ \text{Constant of Proportionality} = \frac{640 \text{ miles}}{32 \text{ gallons}} = 20 \text{ miles per gallon} \]

Therefore, the constant of proportionality is 20 miles per gallon.
