Answer:
21,120 feet
Step-by-step explanation:
To start off this problem, we need to find how many miles James walks per hour. To do that, lets divide 12 by 3.
[tex]x=\frac{12}{3}[/tex]
[tex]x=4[/tex]
Next, since 1 mile = 5,280 feet, we need to multiply 4 by 5,280:
[tex]x=4(5,280)[/tex]
[tex]x=21,120[/tex]
Kendra walked 21,120 feet per hour.
