Question:

Marion is driving between two towns that are close together.

If she drives 1/5 the distance of the trip in 15 minutes, what is her rate per hour?

Ratio and Proportion

Ratio and Proportion are two concepts that are related to fractions and decimals. These concepts involve quantities that are part of a whole. Solving problems on ratio and proportions involve skills manipulating algebraic equations.

Answer and Explanation:

The rate of travel or speed is given by:

{eq}rate=\dfrac{distance}{duration\,of\,travel} {/eq}

1/5 of the distance can be traveled in 15 minutes. If he travel for a whole for 60 minutes or 1 hour, Marion will be able to travel 4 times that distance. Let {eq}d {/eq} be the distance of the whole trip.

{eq}\dfrac{d}{5} \times 4 = \dfrac{4}{5} {/eq}

This means that Marion travels {eq}\dfrac{4d}{5} {/eq} per hour.
