Answer:2.5 cups
Step-by-step explanation:
Given
Rosanne runs 6 miles in an hour
If she drinks 0.5 cups of water every [tex]\frac{1}{3}[/tex] of an hour
So in 1 hour Rosanne drinks 1.5 cups
So, for 6 miles Rosanne drinks 1.5 cups
i.e. For [tex]1\ mile \quad \equiv \quad \frac{1}{4}\ \text{cup}[/tex]
for [tex]10\ mile\quad \equiv \quad \frac{10}{4}\ \text{cup}[/tex]
[tex]=2.5\ \text{cup}[/tex]
