Unit Rate and Climbing Calculations

The lesson introduces unit rate and percentages using the Burj Khalifa as an example. It covers calculating the time to wash all windows and the distance climbed by a professional climber using unit rates. The lesson emphasizes the usefulness of unit rates in solving various problems.

What is the main focus of today's lesson?

• Solving algebraic equations

• Understanding unit rate

• Calculating percentages

• Learning about the Burj Khalifa
