b. From where the shoes spilled (48°N, 161°W) to where they were found on May 22nd 1996 (54°N, 133°W), how many kilometers did they travel? How many days did they take to travel that distance (use April 30 as the date found) ? What was their rate of travel in kilometers per hour?

To find kilometers using latitude and longitude:

distlon = lon2 - lon1 = 133-161 = - 23

distlat = lat2 - lat1 = 54-48 = 6

a = (sin (distlat/2)) ^2 + cos (lat1) * cos (lat2) * (sin (distlon/2)) ^2

a = (sin (6/2) ^2 + cos (48) * cos (54) * sin (-23/2) ^2

c = 2 * arctan2 (sqroot (a), sqroot (1-a))

d = R * c (where R is the radius of the Earth, 6373 km's)

d = 2052 km's

April 30th to May 22nd is 23 days.

23 days x 24 hours per day = 552 hours.

Rate of travel = 2052 / 552 = 3.717 km per hour (round answer as needed.)
