To find out how many words James can type in 30 seconds, we can use the ratios from the table.
From the table, we see that when the time is 20 seconds, James types 40 words.
We can set up a ratio to find the number of words typed in 30 seconds:
40 words / 20 seconds = x words / 30 seconds
To solve for x, we can cross multiply:
40 * 30 = 20 * x
1200 = 20x
x = 60
Therefore, James can type 60 words in 30 seconds.
To find out how many words James can type in 30 seconds, we can use the table of equivalent ratios.
First, let's look at the ratio of words to time for the known data points. We know that in 20 seconds, James can type 40 words.
So, the ratio of words to time is 40:20.
To find out how many words James can type in 30 seconds, we can set up a proportion using the ratio from the table:
40/20 = x/30
To solve for x, we cross multiply:
20x = 40 * 30
20x = 1200
Finally, we divide both sides by 20 to solve for x:
x = 1200/20
x = 60
Therefore, James can type 60 words in 30 seconds.
To answer the question, we need to find the value of x in the table. We know that James can type 40 words in 20 seconds.
From the table, we can see that there is a ratio between time and words typed. We can set up a ratio equation using the given information:
40 words / 20 seconds = x words / 30 seconds
To find the value of x, we can cross multiply:
40 * 30 = 20 * x
1200 = 20x
Dividing both sides of the equation by 20:
1200 / 20 = x
x = 60
Therefore, James can type 60 words in 30 seconds.
