Answer: the woman drives 16.9 miles before she stops for coffee
Explanation:
A woman drives 169/4 miles to work each day. She stops for coffee at a shop that is 2/5 of the way to her job.
To determine how far the woman drives before she stops for coffee, we will multiply the total miles to her job each day by the fraction of the total miles that she drives before stopping at the coffee shop. It becomes
2/5 × 169/4 = 16.9 miles
