Answer:
The correct answer is 1/2 of a mile.
Explanation:
Distance from Carrie’s House to the park = 3/4 of a mile
Distance from Carrie's House to the place she stopped for a drink = 2/3 of the way
Distance walked by Carrie when she stopped for a drink = 2/3 * 3/4 miles
Distance walked by Carrie when she stopped for a drink = 2/3 * 3/4
Distance walked by Carrie when she stopped for a drink = 6/12
Distance walked by Carrie when she stopped for a drink = 1/2 of a mile (simplifying by 6 the numerator and the denominator)
Carrie had walked 1/2 of a mile when she stopped for a drink, before arriving to the park.
