Sara can type 90 words in 4 minutes about how many would you expect her to type in 10 minutes at this rate

Well, first, the unit rate is:

90 : 4 = about 22.5, and 22.5x10=225 words in 10 minutes.

First, we need to calculate the number of words she can type in 1 minute.

We can do this by dividing 90 by 4.

90 / 4

= 22.5

Whcih means she can type 22.5 words in 1 minute.

Now we can multiply this number by 10, so that we can know how many words she can type in 10 minutes

22.5 x 10

=225

Therefore, the answer is 225 words.
