Answer:
Billy walked 132,000 yards last week
Step-by-step explanation:
* Lets explain how to solve the problem
- Billy walks 15 miles every day to soccer practice
- Billy had 5 practices last week
- We want to now Billy walked how many yards last week
* Lets find how many miles did Billy walk the last week
∵ Billy walks 15 miles every day to soccer practice
∵ He had 5 practices last week
∴ He walked = 15 × 5 = 75 miles last week
* Now lets change the mile to yard
∵ 1 mile = 1760 yards
- Multiply the number of miles that Billy walked last week by 1760
 to change it from mile to yard
∵ Billy walked 75 miles last week
∵ 75 miles = 75 × 1760 = 132,000 yards
∴ Billy walked 132,000 yards last week
