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.
To find how many words James can type in 30 seconds, we need to look at the corresponding value in the table.
In the table, we can see that James can type 40 words in 20 seconds and 50 words in 25 seconds.
Since the time interval between 20 seconds and 25 seconds is 5 seconds, and within this time interval James is able to type 50-40=10 words, we can find the rate at which James types words per second.
The rate at which James types words per second is 10 words / 5 seconds = 2 words per second.
Therefore, to find the number of words James can type in 30 seconds, we can multiply the rate per second by 30 seconds:
Number of words = 2 words/second * 30 seconds = 60 words.
Therefore, James can type 60 words in 30 seconds.
To find the answer, we can first calculate the typing rate of James by finding the number of words typed per second.
From the given information, we know that James can type 40 words in 20 seconds. So, the typing rate would be 40 words / 20 seconds = 2 words per second.
Now, we can use the calculated typing rate to find the number of words James can type in 30 seconds.
30 seconds * 2 words/second = 60 words.
Thus, James can type 60 words in 30 seconds.
