Answer :
It t will take Lydia 15 minutes to type 600 words, as per the proportion of her speed of typing. So the correct answer is (C).
To solve this problem, we can set up a proportion based on the information given.
We know that Lydia can type 80 words in 2 minutes. Using this information, we can say that the ratio of words typed to time taken is 80 words/2 minutes.
Now, we can set up another ratio using the given information. We need to find out how long it will take Lydia to type 600 words. Let's say this time is "x" minutes.
Therefore, the ratio of words typed to time taken for 600 words is 600 words/x minutes.
Since both ratios represent the same person (Lydia) and the same activity (typing), the ratio of these two ratios should be equal. So we can set up the following equation:
80 words/2 minutes = 600 words/x minutes
To solve this equation, we can cross-multiply:
80 × x = 600 × 2
80x = 1200
Now we can solve for x by dividing both sides of the equation by 80:
x = 1200/80
x = 15
Therefore, it will take Lydia 15 minutes to type 600 words.
So the correct answer is C) 15 min.

To find out how long it will take Lydia to type 600 words, we can set up a proportion using the information given. The correct answer is C) 15 minutes.
We know that Lydia can type 80 words in 2 minutes. So, we can set up the following proportion:
80 words / 2 minutes = 600 words / x minutes
To solve for x, we can cross-multiply and solve for x:
80 * x = 600 * 2
80x = 1200
Next, we can divide both sides of the equation by 80 to solve for x:
x = 1200 / 80
x = 15
So, it will take Lydia 15 minutes to type 600 words.
Therefore, the correct answer is C) 15 minutes.
