Answer:
Approximately 13 miles
Step-by-step explanation:
First, multiply the amount of Snickers bars eaten by the amount of calories a single Snickers bar is worth:
4 * 215 = 860
4 Snickers bars is worth 860 calories.
Now that we know the amount of calories 4 Snickers bars is worth, divide that amount by the amount of calories burned per mile walked:
860 ÷ 65 ≈ 13.23
You would have to walk approximately 13 miles to burn off the calories from 4 Snickers bars.
