    Figure 2.3.3: Train

    Cara is riding in the South Train leaving Los Angeles and heading towards San Diego. Madeline is riding in the North Train leaving San Diego and heading towards Los Angeles. The South Train is traveling 84mph while the North Train is traveling 92mph. The distance between the two cities is 132 miles. Assuming the trains leave at the exact same time, how long will it take them to meet? (Hints: Draw it out and set up a proportion.)

    Partner Activity 3

    One number is four times as large as another number, and their sum is 5285. What are the two numbers? (Show your solution with squares.)

    Practice Problems

    1. Grade 1: Some bikes and trikes are on the playground. There are seven seats and nineteen wheels. How many bikes are there? How many trikes are there? (Solve without using Algebra.)
    2. Grade 2: Pam has three quarters. She wants to buy candy, which costs 54¢. How much change will she have after she buys the candy?
    3. Grade 3: It takes a rocket 8 seconds to complete one mile. How long will it take the rocket to travel 7 miles?
    4. Grade 4: Irwin decided to create designs using his cereal. In total, he created nine designs and used 63 pieces of cereal. How many cereal pieces were used in each design? Was there an equal number of pieces in each design?
    5. Grade 5: Leo has 10 animals at his ranch: turtles, bunnies and chickens. If there were 5 turtles, and 3 bunnies, what fraction of the animals are chickens?
    6. Grade 6: Ellen wants to build a rectangular fence in her yard, 10 meters by 8 meters. The hardware store owner suggests installing a post every 2 meters. The posts cost $3.42 each. Ellen will also need to buy a glass wall to place in-between each post. The glass costs $50.84 per meter. She also needs to buy one gate for $31.99. How much do all of the materials cost before tax?
