How do you calculate rates?
Use the formula r = d/t.
Your rate is 24 miles divided by 2 hours, so: r = 24 miles ÷ 2 hours = 12 miles per hour..
What is the difference between unit rate and ratio?
The ratio is the relationship of two numbers. … A rate is a little bit different than the ratio, it is a special ratio. It is a comparison of measurements that have different units, like cents and grams. A unit rate is a rate with a denominator of 1.
Is a ratio a rate Yes or no?

What is the difference between ratio rate and proportion?
A ratio compares the magnitude of two quantities. When the quantities have different units, then a ratio is called a rate. A proportion is a statement of equality between two ratios.
How do you compare a ratio?
To compare ratios, you need to have a common second number. By multiplying each ratio by the second number of the other ratio, you can determine if they are equivalent. Multiply both numbers in the first ratio by the second number of the second ratio.
How can you tell when a rate is a unit rate?
When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. If you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.
