Math Problem Statement

A bicyclist rides one fourth mile in StartFraction 1 Over 44 EndFraction hour. Write this rate as a unit rate.

Solution

To find the unit rate, we need to express the bicyclist's speed in miles per hour. The cyclist rides 14\frac{1}{4} mile in 144\frac{1}{44} hour.

We can calculate the speed by dividing the distance (miles) by the time (hours):

Speed=14 mile144 hour=14×441=444=11 miles per hour\text{Speed} = \frac{\frac{1}{4} \text{ mile}}{\frac{1}{44} \text{ hour}} = \frac{1}{4} \times \frac{44}{1} = \frac{44}{4} = 11 \text{ miles per hour}

Thus, the unit rate is 11 miles per hour.
