Bob lives 1/3 miles from the school. He rides the bus to school every morning, but sometimes walk home after school. If Bob had walked a total of 5 miles., how many times has he walked home from school?
Bob lives 1/3 miles from the school, and every morning he rides the bus to school. Let's assume Bob walked home x times after school.
Total distance walked by Bob = 1/3 * x = 1/3x miles
Given that Bob walked a total of 5 miles, the equation becomes:
1/3x = 5
x = 5 * 3 = 15
Therefore, Bob has walked home from school 15 times.
