To determine the number of words Janae types per minute, we need to identify the consistent pattern in the given data. Here’s a step-by-step approach:
1. Understand the problem: We need to calculate Janae's typing speed in terms of words per minute using the given data.
2. Identify the data points:
- At 5 minutes, Janae types 150 words.
- At 10 minutes, Janae types 300 words.
- At 15 minutes, Janae types 450 words.
- At 20 minutes, Janae types 600 words.
3. Calculate the words per minute:
- Using the data from 5 minutes and 150 words as a sample calculation:
[tex]\[ \text{Words per minute} = \frac{\text{Words typed}}{\text{Time}} = \frac{150 \text{ words}}{5 \text{ minutes}} \][/tex]
4. Perform the division:
[tex]\[ \text{Words per minute} = \frac{150}{5} = 30 \][/tex]
5. Check for consistency:
- At 10 minutes, 300 words:
[tex]\[ \frac{300 \text{ words}}{10 \text{ minutes}} = 30 \text{ words per minute} \][/tex]
- At 15 minutes, 450 words:
[tex]\[ \frac{450 \text{ words}}{15 \text{ minutes}} = 30 \text{ words per minute} \][/tex]
- At 20 minutes, 600 words:
[tex]\[ \frac{600 \text{ words}}{20 \text{ minutes}} = 30 \text{ words per minute} \][/tex]
Each calculation confirms the pattern holds true for all given data points.
6. Conclusion:
Janae consistently types at a rate of 30 words per minute across all time intervals.
Therefore, the correct statement is:
Janae types 30 words each minute.
