To determine the minimum typing speed Marshall needs, divide the remaining words by the available time:
**550 words ÷ 25 minutes = 22 words per minute**.

At 22 words per minute, Marshall would finish exactly on time. Since the question asks for the **minimum** required speed, he cannot type slower than 22.

GPT-4o To determine how fast Marshall must type to complete his paper on time, we divide the total number of words he has left to type by the number of minutes he has remaining.

\[ \text{Words left to type} = 550 \]
\[ \text{Minutes remaining} = 25 \]

\[ \text{Required typing speed} = \frac{550 \text{ words}}{25 \text{ minutes}} = 22 \text{ words per minute} \]

So, Marshall must type at least 22 words per minute to finish his paper on time.

minimax To find out the minimum typing speed Marshall needs to finish his paper on time, we divide the total number of words he has left to type by the number of minutes he has until class starts.

Total words left to type: 550 words
Time until class starts: 25 minutes

Minimum typing speed = Total words / Time (in minutes)
Minimum typing speed = 550 words / 25 minutes
Minimum typing speed = 22 words per minute

So, the correct answer is:

C. 22 words per minute

kimi To determine the minimum typing speed Marshall needs to finish his paper on time, we divide the total number of words he has left to type by the total number of minutes he has left.

Total words left: 550
Total minutes left: 25

Minimum typing speed = Total words left / Total minutes left
Minimum typing speed = 550 / 25
Minimum typing speed = 22 words per minute

Answer: C. 22 words per minute

zhipu To determine how fast Marshall must type to finish his paper on time, we need to divide the total number of words left by the time available in minutes.

Given:
- Total words left to type: 550 words
- Time available: 25 minutes

The typing speed required is calculated as:
\[ \text{Typing speed} = \frac{\text{Total words}}{\text{Time available}} \]
\[ \text{Typing speed} = \frac{550 \text{ words}}{25 \text{ minutes}} \]
\[ \text{Typing speed} = 22 \text{ words per minute} \]

Therefore, Marshall must type at least 22 words per minute to finish his paper on time.

The correct answer is:
C. 22 words per minute

deepseekv3 To determine how fast Marshall must type to finish his 550-word paper in 25 minutes, we calculate the required typing speed as follows:

\[
\text{Typing speed} = \frac{\text{Number of words}}{\text{Time in minutes}} = \frac{550}{25} = 22 \text{ words per minute}
\]

For Marshall to finish on time, he must type at least **22 words per minute**.
