Answer 1

Let's find his wpm (words per minute rate). 

153 words / 3 minutes
/3                     /3
51 words / 1 minute

51 words * 10 minutes = 510

He can type 510 words in 10 minutes

Answer 2

The answer would be 510 because if you divide 153 by 3 you will get 51 .
Then you would have to multiply 51 by 10 to 510. And that would be your answer.
