Answer:

2.86 miles.

Step-by-step explanation:

We have been given that Megan uses a pedometer to find how many steps she takes each school day. she took 32,410 steps over the course of 5 days.

$\text{Steps per day}=\frac{32410}{5}$

$\text{Steps per day}=6482$

$\text{Inches in 6482 steps}=6482\times 28$

$\text{Inches in 6482 steps}=181496$

1 feet = 12 inches.

$\text{Feet in 6482 steps}=\frac{181496}{12}$

$\text{Feet in 6482 steps}=15124.666666$

$\text{Miles in 6482 steps}=\frac{15124.666666}{5280}$

$\text{Miles in 6482 steps}=2.8645$

$\text{Miles in 6482 steps}\approx 2.86$

Therefore, Megan walks 2.86 miles on Monday.
