Question

Another gray seal, Gracie, has also been tracked recently, using a tracking microchip attached to her flipper. This allows scientists to track her movement in the ocean to see her exact location. The following lines of code represent the latitude and longitude of Gracie's location over time.

lat = [40.59, 40.52, 40.621, 40.519, 40.56, 41.265, 40.61, 40.806, 41.259, 41.265, 41.264, 41.264, 41.259, 41.262, 41.263]
lon = [69.532, 69.419, 69.354, 69.263, 69.478, 79.885, 69.706, 78.331, 70.815, 78.823, 70.815, 78,81, 78.824, 79.811, 70.811]
Write a program to calculate the farthest in each direction that Gracie was located throughout her travels. Add four print statements to the lines of code above that output the following, where the number signs are replaced with the correct values from the correct list:

A) Farthest north - #
B) Farthest west #
C) Farthest south - #
D) Farthest east =#

Answer 1

The student's task is to find the farthest directions Gracie the gray seal traveled based on the given latitude and longitude lists. The farthest directions are found by identifying the maximum and minimum values from these lists. Correcting a typo in the longitude list allows for the accurate determination of these points.

Step-by-step explanation:

To find the farthest points in each direction that Gracie the gray seal has been, we need to analyze the lists of latitude and longitude values.

To find the farthest north, we look for the maximum latitude. To find the farthest south, we look for the minimum latitude. For the farthest east, we look for the maximum longitude, and for the farthest west, the minimum longitude.

However, there seems to be some input errors in the longitude list. So, let's assume the correct values are all positive, and '78,81' should be '78.81' instead, following standard decimal notation. Let's continue with the fixed longitude values:

Farthest north - The maximum value from the latitudes list.

Farthest west - The minimum value from the longitudes list (assuming the longitudes are all expressed in positive values as they should either be all-west or all-east for a reliable comparison in this context).

Farthest south - The minimum value from the latitudes list.

Farthest east - The maximum value from the longitudes list.

Now, we can write our Python code:

lat = [40.59, 40.52, 40.621, 40.519, 40.56, 41.265, 40.61, 40.806, 41.259, 41.265, 41.264, 41.264, 41.259, 41.262, 41.263]
lon = [69.532, 69.419, 69.354, 69.263, 69.478, 79.885, 69.706, 78.331, 70.815, 78.823, 70.815, 78.81, 78.824, 79.811, 70.811]

print("A) Farthest north -", max(lat))
print("B) Farthest west ", min(lon))
print("C) Farthest south -", min(lat))
print("D) Farthest east =", max(lon))
