Assigned: 090208, Due: 090408 (in class)

G151 homework for calculations to be done by hand, on paper, with all 
work shown. The work to be show should be exactly, or very nearly so, 
the same shown in the linked examples; I want to see the work, the answer 
being correct isn't all that important. Show all units, circle answer, 
show all conversions, be neat ...

conversions: 

	1 in = 2.54 cm
	1 ft = 12 in
	1 mi = 5280 ft
	1 ac = 43560 sq. ft
	1 km = 1000 m
	1 m = 100 cm
	1 m = 3.28 ft 

* units labeled according to ISO standard unit abbreviations
* inches as in and ", feet as ft and '

PROBLEMS: 

-- conversion -- 

1) convert 2.7 cm to in
2) convert 2.3 mi to km
3) convert 4 sq km to ac 

1.1) convert 1.5 in to cm
2.1) convert 6 km to mi
3.1) convert 200 ac to sq. mi 

-- scale calculations -- 

map scale = 1:24,000 

4) convert a distance measured on a paper map of 9" to a 
real world distance in mi 

5) convert a distance measured on a paper map of 4.5 cm
to a real world distance in mi 

6) for a measured area on a paper map of 5" x 6", how 
large is this in real world units of sq. km?, how large
is this area in sq. mi? 

-- extra credit -- 

measured paper map distance = 5 cm, real world (know)
distance = 2 mi 

what is the scale of the paper map?
