Maureen walked 3 miles how many feet did she walk

Ostrovityanka [42]

Answer:

15,840 feet.

Step-by-step explanation:

We have been given that Maureen walked 3 miles. We are asked to convert the distance walked by Maureen in feet.

Since we know that 1 mile equals 5,280 feet, so to convert our given distance we will multiply 3 by 5,280.

$\text{Number of feet Maureen walked}=\text{3 miles}\times \frac{5,280\text{ feet}}{\text{Mile}}$

$\text{Number of feet Maureen walked}=3\times 5,280\text{ feet}$

$\text{Number of feet Maureen walked}=15,840\text{ feet}$

Therefore, Maureen walked 15,840 feet.
