Ivan can type 54 words in 3 minutes.
At this rate, how many words can he type in 10 minutes
To find out how many words Ivan can type in 10 minutes, we can set up a proportion:
54 words / 3 minutes = x words / 10 minutes
Cross multiplying, we get:
3 * x = 54 * 10
3x = 540
x = 540 / 3
x = 180
Therefore, Ivan can type 180 words in 10 minutes.
