1mile=1.6kilometers1liter=0.265gallon1gallon=3.77liters

The equation for converting the miles per gallon figures of Toyota Prius Hybrid in to kilometers per liter is as follows:

Kilometers per literofToyota Prius Hybrid=Miles per gallonofToyota Prius Hybrid×1.6kms3.77liter

Substitute the given values in following equation:

Kilometers per literofToyota Prius Hybrid=50mpg×1.6kms3.77liter=80kms3.77liter=21.22kpl

Similarly, the miles per gallon figures can be converted into kilometers per liter for all the models.

Therefore, the amount of gasoline used by each car annually if it was driven 19,300 kilometers (12,000 miles) per year can be calculated as follows:

The amount of gasoline used by each car annuallyinliters=DistancedrivenbythecarperyearKilometersperliter

To calculate the amount of gasoline used by Toyota Prius Hybrid annually if it was driven 19,300 kilometers (12,000 miles) per year, substitute the given values in the equation. Then, the following value is obtained:

The amount of gasoline used by Toyota Prius Hybridannuallyinliters=19300kilometers21.22kpl=909.52liters Similarly, the amount of gasoline used by each car can be calculated.

The equation for calculating the amount of carbon dioxide released into the atmosphere each year is as follows:

{The amount of carbon dioxide releasedintothe atmosphere each yearbyacar}=(Annual Liters of Gasolineused by acar)×(Amountofcarbondioxidereleasedbyoneliterofgasoline)

Substitute the given values in the equation to calculate the amount of carbon dioxide released into the atmosphere each year. Then, the following is obtained:

{The amount of carbon dioxide releasedintothe atmosphere each yearbyToyota Prius Hybrid}=909.52liters×2.3kg=2091.89kilograms

Discussion Question: Glacial (or Ice) and Periglacial Landscapes A+ The Ice and Glaciers chapter focuses on the Cryosphere, the ice on our planet. I always find it interesting to consider the Earth's Hydrologic Cycle, our water in all of the different phases: solid ice, liquid water, and water vapor (a gas). In place number one for the majority of the World's water, we have the oceans. In place number two, we have ice. Neither one is available to us for drinking water at this point. Amazingly enough, in place number three is groundwater before lakes and streams. Water has led to many problems in the history of California, the United States, and even the world.
