Answer:
To determine how many words you can type in 18 minutes, we can use a simple proportion:
If you can type 480 words in 12 minutes, then the rate at which you type is 480 words / 12 minutes = 40 words per minute.
Now, we can use this rate to calculate how many words you can type in 18 minutes:
Words typed = Rate × Time
Words typed = 40 words/minute × 18 minutes
Words typed = 720 words
Therefore, you can type approximately 720 words in 18 minutes.
