Ricardo can type 39 words per minute. estimate the number of words he can type in 18 minutes.

Hello!

In order to find how many words Ricardo can type in 18 minutes, you'll need to subtract 39 by 18. You'll need to multiply because Ricardo is typing 39 words per minute for 18 minutes so you'll need to multiply to get the number of words he types for 18 minutes. Once you've multiplied 39 with 18, you should have a word count for 702 words for 18 minutes.

So Ricardo can type 702 words per minute.

I hope this helps!
