Understanding Unit Rates and Calculations

The video tutorial explains how to calculate the unit rate of a plane traveling 2,440 miles in 4 hours. It introduces the concept of unit rate as the number of miles per one unit of time, specifically hours. The tutorial demonstrates converting the given rate into a unit rate by simplifying the fraction so that the denominator equals one. The calculation process involves dividing both the numerator and the denominator by 4, resulting in a unit rate of 610 miles per hour.

What is a unit rate?

• A rate with a numerator of one

• A rate with a denominator of one
