Aria needs 3 cups of flour for every 2 cups of sugar. With 9 cups of flour, we set up a ratio: 9 flour / 3 flour = 3. Then, 3 * 2 sugar = 6 cups of sugar. Thus, she needs 6 cups of sugar.

Liam and Abigail are on a road trip adventure! They drove 180 miles in just 3 hours. Can you help them figure out their car's speed in miles per hour?

• 65 miles per hour

Answer explanation

To find the speed, divide the distance by the time. Liam and Abigail drove 180 miles in 3 hours. So, 180 miles ÷ 3 hours = 60 miles per hour. Therefore, the correct answer is 60 miles per hour.
