The map below is the given weather map which shows partial weather station data for several cities in eastern North America.
Step 2

Isotherm lines are drawn at a 10$^circ$ intervals. Temperatures lower than the isotherm value are always on one side of the isotherm and
higher temperatures are consistently on the other side. ![‘slader’]
higher temperatures are consistently on the other side. ![‘slader’]
Exercise 30
Step 1
1 of 5
The map generated from problem 29 is shown below. The needed data from the map are the following:
$$ begin{aligned}
text{Richmond, Virginia temperature}&= 50^circ text{F} \
text{Hatteras, North Carolina temperature} &= 60^circ text{F}\
text{Distance between Richmond and Hatteras} &= 200 text{ miles}
end{aligned} $$
$$ begin{aligned}
text{Richmond, Virginia temperature}&= 50^circ text{F} \
text{Hatteras, North Carolina temperature} &= 60^circ text{F}\
text{Distance between Richmond and Hatteras} &= 200 text{ miles}
end{aligned} $$
Step 2
2 of 5
(a) The equation for gradient is given by:
$$ begin{aligned}
text{gradient} &=frac{text{change in (amount of) field value}}{text{change in distance (horizontal distance}}\
end{aligned} $$
$$ begin{aligned}
text{gradient} &=frac{text{change in (amount of) field value}}{text{change in distance (horizontal distance}}\
end{aligned} $$
Step 3
3 of 5
(b) Plug known values in the equation in (a):
$$ begin{aligned}
text{gradient} &=frac{60^circ text{F}-50^circ text{F} }{200 text{ miles}}\
end{aligned} $$
$$ begin{aligned}
text{gradient} &=frac{60^circ text{F}-50^circ text{F} }{200 text{ miles}}\
end{aligned} $$
Step 4
4 of 5
(c) The average gradient is given by:
$$ begin{aligned}
text{gradient} &=frac{60^circ text{F}-50^circ text{F} }{200 text{ miles}}\
&=frac{10^circ text{F} }{200 text{ miles}} \
&=boxed{textbf{$0.05 dfrac{^circ text{F}}{text{mile}}$}}
end{aligned} $$
$$ begin{aligned}
text{gradient} &=frac{60^circ text{F}-50^circ text{F} }{200 text{ miles}}\
&=frac{10^circ text{F} }{200 text{ miles}} \
&=boxed{textbf{$0.05 dfrac{^circ text{F}}{text{mile}}$}}
end{aligned} $$
Result

$0.05 ^circ text{F per mile}$
Exercise 31
Step 1
1 of 3
Gradients can be estimated by observing how close the isolines between each other. If two isolines are closer together on a field map, the greater the gradient. And if two isolines are farther, the smaller the gradient.
Step 2

Based on the isolines in the map below, the city which is farthest from the isolines is New Orleans.

The given topographic map below shows a location where a series of students went camping using mountain bicycles on July 1, 2003.
Step 2

On July 2, 2003, they moved their campsite 1 mile directly east of their original campsite. The map below shows a plot of the new campsite established by the students.
Exercise 42

The map below shows the location of the campsite on July 2.
Step 2

We will draw the route in along the same elevation, and between two contour lines that are far apart so that they will travel in the least change in elevation. The map below shows the route from the new campsite to point P with the least change in elevation.
