Prereq Unit Rates (Prove it)

Front

What is a unit rate?

Back

A unit rate is a ratio that compares a quantity to one unit of another quantity, often expressed as 'per' something, such as miles per hour or cost per item.

Front

How do you calculate a unit rate?

Back

To calculate a unit rate, divide the quantity by the number of units. For example, if a car travels 300 miles in 5 hours, the unit rate is 300 miles ÷ 5 hours = 60 miles per hour.

How far does Alex travel in 10 minutes if she rides 5 miles in 25 minutes?

Back

Alex travels 2 miles in 10 minutes (5 miles ÷ 25 minutes = 0.2 miles/minute; 0.2 miles/minute * 10 minutes = 2 miles).

Front

If Tom can build 7 paper airplanes in 14 minutes, what is his rate of building airplanes?

Back

Tom's rate is 0.5 airplanes per minute (7 airplanes ÷ 14 minutes).

Front

How many paper airplanes can Tom build in 42 minutes?

Back

Tom can build 21 paper airplanes in 42 minutes (0.5 airplanes/minute * 42 minutes = 21 airplanes).

Front

What is the relationship between distance, rate, and time?

Back

The relationship is expressed as: Distance = Rate × Time.
