If a car travels 200 miles in 4 hours, what is the constant of proportionality?

Question

206 miles per hour
50 miles per hour
204 miles per hour
800 miles per hour

Answer 1

To find the constant of proportionality, you need to determine the speed of the car. The speed can be calculated using the formula:

\[ \text{Speed} = \frac{\text{Distance}}{\text{Time}} \]

In this case, the distance is 200 miles and the time is 4 hours.

\[ \text{Speed} = \frac{200 \text{ miles}}{4 \text{ hours}} = 50 \text{ miles per hour} \]

So, the constant of proportionality, which represents the speed of the car, is 50 miles per hour.
