To find out how far Marsha has driven, we need to calculate \( \frac{2}{5} \) of the total distance of 625 miles.
We can do this calculation as follows:
\[ \text{Distance driven} = \frac{2}{5} \times 625 \]
Calculating \( \frac{2}{5} \times 625 \):
- First, divide 625 by 5:
\[ 625 \div 5 = 125 \]
- Next, multiply the result by 2:
\[ 125 \times 2 = 250 \]
So, Marsha has driven 250 miles.
