Final answer:
Becca's typing speed is 45 words per minute. By multiplying this rate by the respective number of minutes, we can see that statement c) Becca can type 135 words in 3 minutes is the correct one.
Step-by-step explanation:
The question involves determining Becca's typing speed and extrapolating that rate to various time intervals. Becca's rate is 90 words in 2 minutes, which means she types at a rate of 45 words per minute. To find out how many words she can type in different time frames, we multiply her rate by the number of minutes.
- For 5 minutes: 45 words/minute x 5 minutes = 225 words (not 180 words)
- For 1 minute: 45 words/minute x 1 minute = 45 words (not 60 words)
- For 3 minutes: 45 words/minute x 3 minutes = 135 words
- For 4 minutes: 45 words/minute x 4 minutes = 180 words (not 200 words)
Based on Becca's typing rate, the correct statement is c) Becca can type 135 words in 3 minutes.
