Answer:
Brett rides a total of three miles to and from school every week.
Step-by-step explanation:
The distance from Brett's house to school is 3/10 of a mile, so roundtrip each day (to and from school) is 3/10 x 2 or 6/10, which is also 3/5. Since Brett rides his bike to school each day, Monday to Friday, we need to take his daily mileage (3/5) and add it each day for five days, or multiply 3/5 by 5. Multiply 3/5 by 5/1 gives us a total of 15/5 which is 3 miles.
