3.5 words per second

Step-by-step explanation:

There are 60 seconds in a minute. To find the words per seconds, We will need to divide the words per minutes of 212 by 60. Let x equal this number.

x=212/60

Do the division

x=3.5333

This rounds down since 3 rounds down

x=3.5

They type at 3.5 words per second

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
