To determine how many words James can type in 30 seconds, we first establish his typing rate based on the information provided.
James types 40 words in 20 seconds. To find his typing rate in words per second, we calculate:
\[ \text{Typing rate} = \frac{40 \text{ words}}{20 \text{ seconds}} = 2 \text{ words/second} \]
Next, we can use his typing rate to find out how many words he can type in 30 seconds:
\[ \text{Words in 30 seconds} = 2 \text{ words/second} \times 30 \text{ seconds} = 60 \text{ words} \]
So, James can type 60 words in 30 seconds.
The correct answer is:
60
