If 3413 steps=1.27 miles, how many steps equal 1 mile?
sattari [20]
Hi there!

3413 steps = 1.27 miles.
To find the amount of steps in 1 mile, we must divide both sides by 1.27.

3413 / 1.27 steps = 1.27 / 1.27 miles
2687.4 steps = 1 mile.
Hence, in order to walk at least 1 mile, we must take 2688 steps.
