Exercise 1: How Far did Erden Travel?
Pick any seven-day period of ErdenŐs travels and post the location (latitude and longitude) and distance (nautical miles) he travels each day using the data from the Data and Information page (1).

Q1. How many nautical miles did Erden travel in a week when you find the total of each dayŐs travel? ____________________ (Remember to label your units)
Exercise 2: How far did Erden Travel in the week?
Using the Distance Generator (2) calculate the distance Erden traveled from Day 1 to Day 7 in the week you chose for Table 1.
(2) Distance Generator: http://www.indo.com/distance/
In the ŇFromÓ box, write the latitude and longitude of ErdenŐs location on Day 1. In the ŇToÓ box, write the latitude and longitude of Day 7. Click on ŇLook it up!Ó button and record the distance traveled in the Total per Week box under column 6.
Q2. Does the sum of the individual days distance traveled (Column 5 Total) match the distance traveled for the week (Column 6 Total) using the Distance Generator? Why or why not? Explain.
Q3. What is ErdenŐs average distance traveled each day using this method?
____________________
Q4. What is ErdenŐs rate of travel, in knots, for the week? _____________________
(Knots = nautical miles per hour)
a) What is the difference between a nautical mile and a statute mail?
Exercise 3: Mapping ErdenŐs Travels
Using the Map Maker (3): (http://www.aquarius.geomar.de/) and (http://www.aquarius.geomar.de/make_map.html), make a map of ErdenŐs daily travels.
Procedure:
In the PLOT LOCATIONS area
The Latitude and Longitude must be re-written in decimal form.
For example, we must change the 131:27:36W, which means 131 degrees, 27 minutes, 36 seconds west, to decimal degrees. To do this, divide the 27 minutes by 60 because there are 60 minutes (nothing to do with time) in a degree, and then add the resulting decimal to the 131 degrees. Do not worry about the seconds in this exercise. (1 degree = 60 minutes)
Divide the 27 minutes by 60: 27 / 60 = 0.450
Add that decimal to the 131 degrees: 131 + 0.450 = 131.450
Then for this Map Maker make the 131.450 negative because it is west.
West longitude is negative, east longitude is positive
South latitude is negative, north latitude is positive
Open the Map Making link (http://www.aquarius.geomar.de/make_map.html) and write the longitude, then a comma Ň,Ó, then the latitude, then a comma Ň,Ó, and then the date as 8/17 on each line/day for the week. The longitude must be written with a negative sign because it is west longitude.
Sample data for Map Making box: longitude, latitude, date
-131.617, 23.883, 813
-131.916, 23.417, 8/14
-131.216, 23.067, 8/15
-131.450, 22.600, 8/16
In the BASIC PARAMETERS area you must put in the ŇboxÓ in which your locations are located. Choose a close but more northerly latitude than your largest location latitude and then a close but more southerly latitude than your smallest latitude. And then repeat this exercise for the most easterly and westerly points as explained on the Map Maker web page.
Then click the ŇCreate MapÓ button at the bottom of the page.

Q5. How does ErdenŐs track differ if you use the locations of all seven days as compared to using the locations of only Day 1 and Day 7?
Revisit Question Q2.
Q2. Does the sum of the individual days distance traveled (Column 5 Total) match the distance traveled for the week (Column 6 Total) using the Distance Generator? ______________ Why or why not? Explain.
Exercise 4: When will Erden Arrive in Australia?
Map 2: Erden's Planned Track
Given the information that you discovered or calculated in Exercise 1 through 3 answer the following questions and the Distance from Bodega Bay, California to Brisbane, Australia as the crow flies is 7053 miles (11350 km) (6129 nautical miles).
(Distance and location data: http://www.oceanrowing.com/ErdenEruc_Pacific/dist.htm)
Q6. At the rate of travel calculated in Q4, how many days will it take Erden to reach Australia?
Q7. On what day and time do you predict Erden will set foot on Australia?
