How to Determine Unit Rate for a Real World Situation

The video tutorial explains how to determine the unit rate from a real-world scenario involving a mail carrier delivering mail to 84 houses in three hours. It breaks down the process of converting the given rate into a unit rate by simplifying the ratio of houses to hours. The tutorial includes a step-by-step calculation to find the unit rate, which is 28 houses per hour.

What is the initial rate given in the problem about the mail carrier?

• 84 houses in 2 hours

• 84 houses in 3 hours

• 84 houses in 5 hours

• 84 houses in 4 hours

Why is it important to include units when expressing a rate?

• Units are only needed for mathematical operations

• Units help in identifying the type of rate

• Units make the rate look more complex

• Units are not necessary for understanding rates

How can the rate of 84 houses in 3 hours be expressed as a ratio?

• 1:84

• 84:3

• 3:84

• 84:1

What is the first step in calculating the unit rate from the given ratio?

• Add the numbers

• Multiply the numbers

• Divide the numbers

• Subtract the numbers

What is the final unit rate of mail delivery per hour?

• 32 houses per hour

• 30 houses per hour

• 28 houses per hour

• 24 houses per hour
