Math Question Help

<p>The distance Danielle walks is directly proportional to the length of time she walks. If she walks a distance of 1 1/3 miles in 20 minutes, how many miles will she walk in 1 hour?</p>

<p>so I set up a proportion and solved the problem and I got 3.9999 ( btw… this was a grid in question from the college board online course)…but on college board it says the answer is 4… and only 4… I put 3.99 but isn’t it like the same thing??</p>

<p>It’s because it’s basically 1 1/3 three times so you add the 1/3s and get 3/3 so its 4. I can see how you got .99 because the calculator converts it to 1.3333333333… hope this terrible explanation helps man. :/</p>

<p>ahah yeah I get it lol
Thank you :))))</p>
