To find out how many words James can type in 30 seconds, we need to look at the table. James typed 40 words in 20 seconds and 50 words in 25 seconds. Since it is a linear relationship, we can find the rate at which James types words and use it to find how many words he can type in 30 seconds.
The rate of typing for James is determined by dividing the change in words by the change in time.
Rate = (change in words) / (change in time)
For James, the rate is (50-40)/(25-20) = 10/5 = 2 words per second.
Now, we can find how many words James can type in 30 seconds by multiplying the rate by the time.
Number of words = rate * time
Number of words = 2 * 30 = 60 words
So, James can type 60 words in 30 seconds.
Use the table to answer the question.
Time (sec) 20 25 30 35
Words Typed 40 50 x 70
James can type 40 words in 20 seconds. How many words can James type in 30 seconds?
