A unit rate is a ratio that compares two different quantities where one of the quantities is expressed as 1. It tells you how much of one thing there is for every single unit of another thing. For example, if you drive 120 miles in 2 hours, the unit rate is 60 miles per hour (120 miles / 2 hours = 60 miles/hour). Unit rates are super useful for comparing prices, speeds, and lots of other things in everyday life!
To find a unit rate, you usually divide the quantity you're interested in by the other quantity to get a rate 'per 1' of the second quantity. Make sure your units are consistent!
