Final answer:
Charlie's reading rate during a two-minute timed reading can be calculated if we know the number of lines or words he read. However, without this information, we cannot provide an exact reading rate.
Step-by-step explanation:
To determine Charlie's reading rate if the lines were read during a two-minute timed reading, we would need to know the number of lines or words that Charlie read. This is a Mathematics question typically seen at the Middle School level involving rates and proportions. Without the specific number of lines or words read by Charlie, we cannot calculate an exact reading rate. Reading rates are typically measured in either words per minute or pages per minute.
For example, if Charlie read 240 words in the allotted two minutes, his reading rate would be:
240 words / 2 minutes = 120 words per minute.
This is a simple division calculation that students usually learn in Middle School mathematics classes. To help a student better understand this concept, one could use various examples of timed readings and corresponding word counts.
