Ratios and Rates: Rates

The video tutorial explains the concept of rates and unit rates. It begins with an introduction to rates using examples like hourly wages. The tutorial then demonstrates how to calculate unit rates through a pulse counting exercise, converting pulses per 10 seconds to pulses per minute. Finally, it provides another example by calculating the unit rate of calories per serving in a box of cereal, dividing total calories by the number of servings.

What is a rate and how is it defined?

If you counted 12 pulses in 10 seconds, what is the unit rate of pulses per minute?

How do you calculate a unit rate from a given rate?

Explain the significance of finding a unit rate in everyday situations.

How many calories are there per serving if a box contains 1,320 calories and has 12 servings?
