Question

You live 3 1/2 miles from school. In the morning, you walk 1/4 mile directly toward school to take the bus. After school, you walk home the same distance when the bus drops you off. How many miles do you ride the bus to and from school each day?

Answer 1

Subtract 1/2 mile for the two-way trip of walking. Then multiply the 3 by 2 to get how far the bus drove.
so the answer would be:
6
