Understanding Unit Rates and Their Applications

Maria Miller from Math Mammoth explains unit rates, which are rates with a second term of one unit. She provides examples, demonstrates how to calculate unit rates from other rates, and applies these concepts to real-life problems. The video also covers handling fractional unit rates and graphing them to understand their slopes.

What is a unit rate?

• A rate where the second term is one unit

• A rate where the first term is one unit

• A rate where the terms are in different units

• A rate where both terms are equal

Which of the following is an example of a unit rate?

• 70 miles per 2 hours

• $8.25 per 2 hours

• $12 per kilogram

• 88 miles per 4 gallons

How do you calculate a unit rate from a given rate?

• Multiply the terms

• Subtract the terms

• Add the terms

• Divide the first term by the second term

If you have 88 miles per 4 gallons, what is the unit rate?

• 88 miles per gallon

• 44 miles per gallon

• 11 miles per gallon

• 22 miles per gallon

What is the unit rate if you walk half a mile in 15 minutes?

• 4 miles per hour

• 3 miles per hour

• 2 miles per hour

• 1 mile per hour

How can you find the unit rate using division for fractional time?

• Multiply the fractions

• Divide the fractions

• Add the fractions

• Subtract the fractions

If you walk two-fifths of a mile in 25 minutes, what is the unit rate in miles per hour?

• 24/25 miles per hour

• 1.2 miles per hour

• 0.96 miles per hour

• 2 miles per hour

How do you convert a rate to a unit rate when the time is not a simple fraction of an hour?

• Add the time units

• Find the rate for a smaller time unit first

• Divide by 60

• Multiply by 60

A bird can fly 2450 kilometers in 20 days. What is the unit rate in kilometers per day?

• 122.5 kilometers per day

• 125 kilometers per day

• 120 kilometers per day

• 130 kilometers per day

How many days would it take for the bird to fly 1500 kilometers at the unit rate?

• 15 days

• 12.24 days

• 10 days

• 20 days
