Her goal

Her goal is to walk 10,000 steps each day. She measures her average step length to be 30 inches. If she walks 10,000 steps in a day, how many miles will she walk?

Correct answer:

x =  4.7348 mi

Step-by-step explanation:

$$\begin{gathered} n=10000 \\ s=30\text{inch}\to \text{ft}=30:12\text{ft}=2.5\text{ft} \\ {x}_1=s\cdot n=2.5\cdot 10000=25000\text{ft} \\ x=x_1/5280=25000/5280=4.7348\text{mi} \end{gathered}$$
