Answer:
1 : 2 cm/km or ![\frac{1}{2} \, \frac{cm}{km}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%20%5C%2C%20%5Cfrac%7Bcm%7D%7Bkm%7D)
One cm represents 2 km.
Explanation:
If 3 cm represents 6 km on the earth, the ratio to consider is: 3 : 6 cm/km which is the same as:
1 : 2 cm/km or ![\frac{1}{2} \, \frac{cm}{km}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%20%5C%2C%20%5Cfrac%7Bcm%7D%7Bkm%7D)
One cm represents 2 km.
Permeability is a measure of how fast a liquid can pass
through a layer of solid. In this case, the lesser the time, the more permeable
the solid is. Or the other way around, the bigger the time, the less permeable
the solid is. Therefore the answer in this problem is:

Ptolemy life is probably my most recommenced
Coulomb's law states<span> that: The magnitude of the electrostatic force of interaction between two point charges is directly proportional to the scalar multiplication of the magnitudes of charges and inversely proportional to the square of the distance between them.

Hello =D
This problem is about cinematic
So
V = 45 mi/h
t = 2 h
Then
V= X/t
X = V*t
Then
X = (45)*(2)
X = 90 mi
