Question

Rosanne is training for the Austin marathon, so she plans to run 10 miles in her neighborhood this weekend. It usually takes her an hour to run 6 miles. If she generally drinks 0.5 cups of water every 1 3 of an hour, how many cups of water will she drink on her run?

Answer 1

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  $\frac{1}{3}$  of an hour

So in 1 hour Rosanne drinks 1.5 cups

So, for 6 miles Rosanne drinks 1.5 cups

i.e. For   $1\ mile \quad \equiv \quad \frac{1}{4}\ \text{cup}$

for    $10\ mile\quad \equiv \quad \frac{10}{4}\ \text{cup}$

$=2.5\ \text{cup}$
