| Place a small "X" on your globe at the southern tip of the state of
Texas near 26N/98W. Starting at that location draw a line in a northerly
direction to southeastern Montana near 46N/106W. What is the distance
between the Texas location and the Montana location? (1.)

| During the 1870's and 1880's teams made up of Mexican vaqueros and
American cowboys herded millions of cattle along cattle trails
from south Texas to northern railroads and markets. The line that you
drew on your globe is the approximate route of one of these trails that
stretched from the Rio Grande River to Miles City, Montana. Name two
major rivers that this trail crossed. (2.)

| Though the great circle distance that you measured between these
locations was about 1600 miles, the actual cattle trail
the cowboys followed was closer to 2,000 miles. If it took a typical
cattle drive about 165 days to make the trip along this route, what was
the average distance covered each day? (3.)
