Wanda walks her daughter .5 miles to school in the morning and then walks .5 miles home. She repeats this when she meets her daughter after school in the afternoon. They walk to school 5 days a week. How many miles does Wanda walk after 4 weeks?
Thoughts? Step-by-step reasoning:
She walks .5 miles to school and back 4 times a day so that's .5 * 4 = 2 miles. She walks 2 miles a day for 5 days so that's 2 * 5 = 10 miles. Over 4 weeks of walking 10 miles per week she walks 4 * 10 = 40 miles.
Thus, the answer is 40.
