Three pointer can point three walls in three minutes. how many pointer are needed to point 27 wall in 9 minutes?
- 27
- 18
- 9
- 3
Explanation
- 3 pointers point 3 walls in 3 minutes.
- So, 1 pointer points 1 wall in 3 minutes.
Now, we want to know how many pointers are needed to point 27 walls in 9 minutes.
Since 1 pointer points 1 wall in 3 minutes, in 9 minutes (which is 3 times longer), 1 pointer can point:
1 wall × 3 = 3 walls.
To point 27 walls in 9 minutes:
Number of pointers needed = Total walls / Walls per pointer = 27 / 3 = 9 pointers.
