It looks like some information is missing in your question, specifically the fraction or decimal that represents the distance Marsha has already driven. If you provide that information, I'd be happy to help you calculate how far she has driven.
For example, if Marsha has driven \( \frac{3}{5} \) of the distance, you would calculate as follows:
- Find \( \frac{3}{5} \) of 625 miles: \[ \text{Distance driven} = \frac{3}{5} \times 625 = 375 \text{ miles} \]
Please provide the fraction or decimal so I can assist you accurately!
