## 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.

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.
