2.1 Using Problem Solving Strategies and Models Math Midterm: March 11

Vocabulary  Verbal Model Writing an equation in words before you write it in mathematical symbols.

Example 1:  A bus travels at an average rate of 55 miles per hour. The distance between Chicago and San Francisco is 2130 miles. How long would it take for the bus to travel from Chicago to San Francisco?

Example 2:  The table shows the height of a jet airplane t minutes after beginning its descent. Find the height of the airplane after 9 minutes.

Example 3:  You want to paint five 1 foot wide stripes on the wall. There should be an equal amount of space between the ends of the wall and the stripes and between each pair of stripes. The wall is 14 feet long. How far apart should the stripes be?

Example 3 cont’d:  Begin by drawing a diagram.

Checkpoint 1. In example 1, how fast is the bus traveling if it takes 22 hours to travel from San Francisco to Colorado Springs, a distance of 1335 miles? Answer: about 60.7 miles per hour 2. In example 3, how far apart do the stripes need to be painted if you are only going to put 4 stripes on the wall? Answer: 2 feet

Checkpoint 3. If a jet airplane descends at the rate given in the table, what is its height after 8 minutes? Answer: 10,400 feet
