2. It takes Amy 28 minutes to solve 4 puzzles.
How long will it take her to solve 14 puzzles?

A) 84 minutes and 98 minutes

B) 42 minutes and 49 minutes

C) 70 minutes and 84 minutes

D) 98 minutes and 112 minutes

Answer 1

It will take Amy 84 minutes to solve 12 puzzles and 98 minutes to solve 14 puzzles.

Step-by-step explanation:

To determine how long it will take Amy to solve 12 puzzles, we can set up a proportion involving the number of puzzles and the time it takes. We can write the proportion as:

4 puzzles / 28 minutes = 12 puzzles / x minutes

Cross multiplying, we get:

4 * x = 12 * 28

x = (12 * 28) / 4

x = 84 minutes

Therefore, it will take Amy 84 minutes to solve 12 puzzles. Similarly, for 14 puzzles:

4 puzzles / 28 minutes = 14 puzzles / x minutes

Cross multiplying, we get:

4 * x = 14 * 28

x = (14 * 28) / 4

x = 98 minutes

Therefore, it will take Amy 98 minutes to solve 14 puzzles.
