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

• A rate with a denominator of zero

• A rate with a numerator of zero

How do you convert a rate to a unit rate?

• Add the same number to both the numerator and denominator

• Subtract the same number from both the numerator and denominator

• Divide both the numerator and denominator by the same number

• Multiply both the numerator and denominator by the same number

What is the first step in simplifying 2,440 miles/4 hours to a unit rate?

• Subtract 4 from the numerator

• Add 4 to the numerator

• Divide the numerator by 4

• Multiply the numerator by 4
