Question

mary ran at a steady speed in a 10-mile race. her finish time was 2 hours. mary can bike the same distance in $\frac{1}{2}$ hour. mary wants to know her running speed and biking speed in miles per hour. which fraction represents marys running speed in miles per hour? $\frac{10}{2}$ what is marys running speed in miles per hour? $\frac{10}{2} = \square$

Explanation:

Step1: Recall the speed formula

The formula for speed is \( \text{speed} = \frac{\text{distance}}{\text{time}} \).

Step2: Identify distance and time for running

Mary ran a distance of 10 miles in a time of 2 hours.

Step3: Calculate running speed

Using the speed formula, her running speed is \( \frac{10}{2} \). To find the value of \( \frac{10}{2} \), we perform the division: 10 divided by 2 is 5.

Answer:

For the fraction representing running speed: \( \frac{10}{2} \)
For the value of \( \frac{10}{2} \): 5
