Answer:
2 miles or 3,520 yards.
Step-by-step explanation:
The distance from Charles's house to his school = 3 miles
1 mile = 1760 yards.
His father gave him a ride for 1,760 yards = 1 mile
He walked the rest of the way that is = 3 miles - 1 mile = 2 miles
Since, 1 mile = 1760
Therefore 2 miles = 1760 × 2 = 3,520 yards.
So Charles walked 2 miles or you can say 3,520 yards.
