Jude types 1,001 characters in 7 minutes. What is her typing rate in characters per minute?

To find Jude's typing rate in characters per minute, we divide the total number of characters typed by the total number of minutes she spent typing.

Jude types 1,001 characters in 7 minutes:

\[
\text{Typing rate} = \frac{\text{Total characters}}{\text{Total minutes}} = \frac{1001 \text{ characters}}{7 \text{ minutes}} \approx 143 \text{ characters per minute}
\]

So, the answer is **B. 143 characters per minute**.
