Hi! You need 3 boxes because if you divide 21 1/4 / 10 you get 2 1/8 or 2.125 so you at least have two boxes. You will still have some left over after the two boxes so you will need another box for those. I hope this helped, Goodluck :)
One because if you put two then the would be 50 and thats over 41
Answer:
They will be at a distance of 16 miles apart from each other.
Step-by-step explanation:
Both Joe and Anita start roller balding in opposite directions, and both of them have the same speed of 4 mph.
As they move oppositely in a straight line therefore, the distance between them will be the distance travelled by each of them's sum.
Distance covered by Joe in 2 hours= 8 miles
Distance covered by Anita in 2 hours= 8 miles
Therefore, the total distance from each other =16 miles
