Question 198044: Please help me solve this problem.
When Bobby walks to school in the morning he walks 6 blocks north to pick up Carrie, then 10 blocks west to Andy's house. From Andy's they walk 4 blocks north to school. There is also a direct path that Bobby could take from his house to school if he went alone. How many fewer blocks would he have to walk if he walked to school alone?
