Answer 2

Answer:

If in 12 seconds 15 words can be typed, then in 5 minutes 375 words can be typed

Step-by-step explanation:

Given

Number of words that can be typed in 12 seconds = 15

So, number of words that can be typed in 1 second = 15/12= 5/4 words

5 minutes = 5*60 seconds= 300 seconds

So the number of words that can be typed in 300 seconds $=\frac{5}{4} *300\\\\=5*75\\\\= 375$

So 375 words can be typed in 5 minutes
