Plan a trip where you will start at one city, travel to a second city, travel to a third city, and then return to the original city. Assuming you could travel the direct straight-line distance between each pair of cities, how far will you travel all together? Write your total distance traveled in both decimal notation and scientific notation. Show all your work so it is clear what cities you are going to and in what order.

1 answer

Let's plan a trip starting from Atlanta, then visiting Chicago, Seattle, and finally returning to Atlanta. We can summarize the distance between the cities using the table provided and perform the calculations.

Step 1: Identify the Distances

From the table:

  1. Atlanta to Chicago: \( 9.444 \times 10^2 \) miles
  2. Chicago to Seattle: \( 2.78657 \times 10^3 \) miles
  3. Seattle to Atlanta: \( 3.50307 \times 10^3 \) miles

Step 2: Calculate the Total Distance

Now we will add all the distances together.

  • Distance from Atlanta to Chicago:
    \[ 9.444 \times 10^2 = 944.4 \text{ miles} \]

  • Distance from Chicago to Seattle:
    \[ 2.78657 \times 10^3 = 2786.57 \text{ miles} \]

  • Distance from Seattle to Atlanta:
    \[ 3.50307 \times 10^3 = 3503.07 \text{ miles} \]

Total Distance Calculation

Now we add the distances: \[ 944.4 + 2786.57 + 3503.07 = 7234.04 \text{ miles} \]

Step 3: Convert the Total Distance to Scientific Notation

To express \( 7234.04 \) in scientific notation: \[ 7234.04 = 7.23404 \times 10^3 \]

Final Result

So the total distance traveled in decimal notation and scientific notation is:

  • Total Distance Traveled (Decimal Notation): \( 7234.04 \) miles
  • Total Distance Traveled (Scientific Notation): \( 7.23404 \times 10^3 \) miles

Recap of Trip Route

  • Start at Atlanta
  • Travel to Chicago
  • Travel to Seattle
  • Return to Atlanta

Total distance traveled:

  • Decimal Notation: \( 7234.04 \) miles
  • Scientific Notation: \( 7.23404 \times 10^3 \) miles
