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

2.5

Explanation:

Answer 2

Answer:2.5 cups

Explanation:

Given

Rosanne runs 6 miles in an hour

If she drinks 0.5 cups of water every
`(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 (1)/(4)\ \text{cup}`

for
`10\ mile\quad \equiv \quad (10)/(4)\ \text{cup}`

`=2.5\ \text{cup}`
