Constant Rate Problems and Applications

The video tutorial covers the concept of constant rate, explaining how to calculate rates using distance, area, and volume. It provides examples involving mowing, water flow, typing, painting, and walking, demonstrating how to set up equations, use proportions, and graph results to make predictions.

What is the formula to calculate the rate when given distance and time?

• Rate = Distance x Time

• Rate = Distance + Time

• Rate = Time / Distance

• Rate = Distance / Time

If Pauline mows 35 square feet in 2.5 minutes, what is her mowing rate per minute?

• 15 square feet per minute

• 14 square feet per minute

• 10 square feet per minute

• 12 square feet per minute

In Pauline's example, how much area can she mow in 10 minutes?

• 120 square feet

• 140 square feet

• 160 square feet

• 100 square feet

What is the rate of water flow from the faucet in gallons per minute?

• 5.5 gallons per minute

• 2.5 gallons per minute

• 3.5 gallons per minute

• 4.5 gallons per minute

How many gallons of water flow out in 4 minutes?

• 14 gallons

• 16 gallons

• 12 gallons

• 18 gallons

What is the equation for the number of pages Juan can type in T minutes?

• P = 3.5 * T

• P = 3.5 / T

• P = 1 / 3.5 * T

• P = T / 3.5

How many pages can Juan type in 10 minutes?

• 5.7 pages

• 4.3 pages

• 2.9 pages

• 3.5 pages

What is Emily's painting rate in square feet per minute?

• 8.4 square feet per minute

• 5.4 square feet per minute

• 7.4 square feet per minute

• 6.4 square feet per minute

How much area can Emily paint in 2.5 minutes?

• 17 square feet

• 15 square feet

• 18 square feet

• 16 square feet

What is the importance of graphing in these constant rate problems?

• It helps in visualizing the data.

• It makes calculations faster.

• It complicates the problem.

• It is not important.
