2. EXAMPLE 1 Use a Formula 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? (Note: Use distance formula)

3. GUIDED PRACTICE 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?

4. EXAMPLE 2 The table shows the height h of a jet airplane t minutes after beginning its descent. Find the height of the airplane after 9 minutes Look for a Pattern Time (min), t01234 Height (ft), h 35,00032,00029,00026,00023,000

5. EXAMPLE 3 You want to paint five 1 ft 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 ft long. How far apart should the stripes be? Draw a Diagram

6. GUIDED PRACTICE If a jet airplane descends at the rate given in the table, what is its height after 8 minutes? Time (min), t01234 Heigh (ft), h 36,00032,80029,60026,40023,200

7. GUIDED PRACTICE 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?
