Answer: 11/12 miles
Step-by-step explanation:
From the question, we are informed that Maria walks 1 7/12 miles and that Joan walks 2 1/2 miles. For us to solve the question, we have to calculate the difference between their miles walked. This will be:
= 2 1/2 - 1 7/12
= 2 6/12 - 1 7/12
= 11/12 miles
The answer is 11/12 miles
