To find out how many words James can type in 30 seconds, we can set up a proportion.
Let's call the number of words James can type in 30 seconds x.
The proportion is:
40/20 = x/30
To solve for x, we can cross multiply:
20x = 40 * 30
20x = 1200
Now we divide both sides by 20 to solve for x:
x = 1200/20
x = 60
Therefore, James can type 60 words in 30 seconds.
