Final answer:
To calculate the total distance run by the 5 seventh graders over 18 practices, multiply their daily distance (6.2 miles) by the number of team members (5) and the number of practices (18), resulting in 558 miles total.
Step-by-step explanation:
The student's question asks for the total distance run by 5 seventh-grade members of the cross-country team over 18 practices, given that each member runs 6.2 miles each day at practice.
To solve this, we need to multiply the daily distance run by each member by the number of team members, and then by the number of practices.
- Multiply the daily distance (6.2 miles) by the number of team members (5).
- Multiply the result from step 1 by the number of practices (18).
- Add up the total to get the final distance.
After performing this calculation, you find that the total distance run by the 5 seventh-grade team members over 18 practices is 558 miles.
