Solving Age and Distance Problems

Mrs. Eppie presents lesson 9 from module 3, focusing on using properties of equality to solve word problems. The lesson includes exercises on solving equations for practice times and calculating distances in a race. It also covers using algebra to determine ages. Key concepts include the use of PEMDAS, the distributive property, and the distance formula.

What is the primary focus of the lesson introduced by Mrs. Eppie?

• Understanding geometry

• Studying historical events

• Solving equations using properties of equality

• Learning about fractions

How many hours per day did Heather practice soccer?

• 4 hours

• 3 hours

• 2 hours

• 1 hour

What is the total time Fred and Sam predict for their bike and run event?

• 15 hours

• 18 hours

• 20.55 hours

• 22 hours

What formula is used to calculate Fred's total distance?

• Distance = Speed x Time

• Distance = Speed - Time

• Distance = Speed / Time

• Distance = Speed + Time

How far did Fred bike during the race?

• 130 miles

What is the total distance Sam ran during the race?

• 28 miles

• 26.2 miles

• 24.5 miles

• 20 miles

In the age problem, how is Shelby's age related to Bonnie's?

• Shelby is twice as old as Bonnie

• Shelby is five times as old as Bonnie

• Shelby is seven times as old as Bonnie

What is Bonnie's present age?

• 9 years

• 12 years

• 10 years

• 11 years

How old will Shelby be in five years if Bonnie is currently 11 years old?

• 82 years

• 72 years

• 77 years

• 66 years

What is the purpose of using a two-way table in the age problem?

• To compare speeds
