Answer:
1000 words
Step-by-step explanation:
You'll have to divide 12 from 600 to find the unit rate. If you divide 12 from 600, you'll get 50. Since we started off with 600/12, we basically just simplified the fraction, so now it's 50/1, which is the unit rate. Now, multiply 1 by 20, which is 20. Since you did that to the denominator, also multiply 20 to the numerator, which gives you 1000. That means 1000/20 is equivalent to 50/1. That also means that Ryan can type 1000 words in 20 minutes.
