Answer:
Maya solve puzzle in 6 minutes per puzzle and Amy solves the puzzle in 7 minutes per puzzle.
Step-by-step explanation:
Given:
For Maya 5 puzzles = 30 minutes
For Amy 4 puzzles = 28 minutes
We need to find the rate at which student solve the puzzle in minutes per puzzle.
Solution:
First we will find the rate of Maya.
5 puzzles = 30 minutes
1 puzzle = Number of minutes for 1 puzzle
By Using Unitary method we get;
Number of minutes for 1 puzzle =
Hence Maya requires 6 minutes for 1 puzzle.
Now we will find the rate of Amy.
4 puzzles = 28 minutes
1 puzzle = Number of minutes for 1 puzzle
By Using Unitary method we get;
Number of minutes for 1 puzzle =
Hence Maya requires 7 minutes for 1 puzzle.
Hence We can say that Maya solve puzzle in 6 minutes per puzzle and Amy solves the puzzle in 7 minutes per puzzle.
