Understanding Units of Measurement

The video tutorial discusses two scenarios: Louisa's lawn mowing business and Cameron's snow pile. Louisa wants to measure how the volume of fuel used increases with the lawn area, requiring a unit of volume per area, such as liters per kilometer squared. Cameron wants to measure how the height of a snow pile increases over time, needing a unit of length per time, like meters per hour. The tutorial guides viewers through analyzing and selecting appropriate units for these measurements.

What is Louisa trying to measure in her lawn mowing business?

• The cost of fuel per liter

• The speed of her lawn mower

• The time taken to mow a lawn

• The rate of fuel usage per area

Which of the following is NOT a suitable unit for measuring volume per area?

• Meter cubed per kilometer squared

• Pint per square foot

• Liters per kilometer squared

• Centimeters per square kilometer

Why is 'liters per minute' not suitable for Cameron's measurement?

• It measures volume per time, not height per time

• It measures height per time

• It measures time per volume

• It measures distance per time

What does 'meters per hour' represent in Cameron's context?

• Distance per area

• Volume per time

• Height per time

• Time per volume

What is the reciprocal of 'meters per hour'?

• Liters per minute

• Kilometers per hour

• Hours per meter

• Minutes per liter
