Final answer:
The sentence 'She runs more than you' indicates that she runs to a greater degree than you do. The word 'than' is a comparison word, utilized as seen in the example where Laura runs a longer distance than Sarah.
Step-by-step explanation:
The sentence 'She runs more than you' means that compared to you, she engages in running to a greater extent, or is capable of running faster, longer, or further. In English, we use the word than to make comparisons between two subjects, in this case, 'she' and 'you'.
To better understand this, consider a previous example where we compared distances run by Sarah and Laura. Sarah was to run 5000 meters, and Laura was to run a 10K, which is equivalent to 10 kilometers.
Upon converting 5000 meters to kilometers, we found that 5000 meters equal 5 kilometers, which is less than the 10 kilometers Laura would run, hence Laura runs a longer distance than Sarah. This illustrates the usage of 'than' for comparisons in both mathematical and everyday contexts.
