Answer:
4,7 miles
Explanation:
The average step length is 30 inches. If she walks 10,000 steps in a day, the distance that she will walk, in inches, is:
10,000 step × (30 in/1 step) = 300,000 in
1 mile is equivalent to 63,360 inches. The miles corresponding to 300,000 inches are:
300,000 in × (1 mi/63,360 in) = 4,7 mi
