Question

Alfred is practicing typing. The first time he tested himself, he could type 27 words per minute. After practicing for a week, he could type 29 words per minute. After two weeks he could type 31 words per minute. Based on this pattern, predict how fast Alfred will be able to type after four weeks of practice.

Answer 1

35 words per minute .the words are increasing by 2 every week

Answer 2

Answer: His speed after four weeks of practice will be 35 wpm.

Explanation:

Since we have given that

Initially he could type = 27 wpm

After one week, he could type = 29 wpm

After two weeks , he could type = 31 wpm

So, According to this pattern, he increases 2 wpm after practicing every week.

So, After three weeks, he could type = 31+2 = 33 wpm

After four weeks of practice, he could type = 33+2 = 35 wpm.

So, his speed after four weeks of practice will be 35 wpm.
