Final answer:
A unit rate is a comparison of two measurements, one of which has a value of 1. It expresses the relationship between different quantities. A unit scale, on the other hand, compares the dimensions of an actual object to the dimensions of a scale drawing or model.
Step-by-step explanation:
A unit rate is a comparison of two measurements, one of which has a value of 1. It is a ratio that expresses the relationship between different quantities. For example, the unit rate of 55 miles per hour means that for every 1 hour, you travel 55 miles. It can be written as 55/1 miles/hour.
A unit scale, on the other hand, is a ratio that compares the dimensions of an actual object to the dimensions of a scale drawing or model that represents the actual object. The unit scale is often used in maps, where it shows the relationship between the distance on the map and the actual distance on the ground. For example, a unit scale of 1 inch = 100 feet means that 1 inch on the map represents 100 feet in the real world.
Unit rate is the ratio of two different units, with denominator as 1. For example, kilometer/hour, meter/sec, miles/hour, salary/month, etc. Arithmetic is probably the most basic and ancient branch of mathematics and is quite commonly used in our day-to-day life. This subject is all about the problems based on numerals and operations upon numerals. We do solve problems of arithmetic intentionally or unintentionally during our daily routine. For example – While purchasing vegetables or fruits, in other dealings or in estimating speed of something etc. Also, learn conversion of units here.
Often we are required to find the price or speed or other factors in the arithmetic problems. A concept that we very commonly come across in arithmetic as well as in practical life, is the unit rate. Rate and unit rate are two different concepts. Though they have the same basic idea, their definitions and usage is a little different. In a metric system there are many units defined. In this article, we shall learn about the unit rate. Let us go ahead and know the definition of unit rate and examples based on it.
