Solve the problem.
I can type 19 words in 38 seconds. How many can I type in 60 seconds?
Choose the best answer from the options below:
A 25
B 30
C 40
D 50
C 40
To solve this problem, we can set up a proportion:
19 words / 38 seconds = x words / 60 seconds
To solve for x, we can cross multiply and divide:
38 * x = 19 * 60
380x = 1140
Divide both sides by 380:
x = 3
Therefore, you can type 30 words in 60 seconds.
The best answer is B.
