Tom left for his friend's house. He drove 60 km in an hour. When he got to John's house, he wondered how fast he had been driving. What formula would he use to determine his speed?

Tom drove 60 km/hr fast

Speed = Distance traveled / time taken

Explanation:

Given that:

Distance traveled by Tom = 60 km

Time taken by Tom = 1 hour

Speed = ?

Since speed is obtained by dividing distance traveled by the time taken, hence the formula to use is as follows:

speed = distance / time

Speed = 60 km / 1 hour

Speed = 60 km/hr

Thus, Tom had been driving 60 km/hr fast, using the formula "speed = distance / time"

so here is the information for current research:

-nrel's geothermal analysts, scientists, and engineers perform a full range of research from developing advanced methods of locating and accessing geothermal resources to exploring innovative technologies to extract and produce clean energy from the heat of the earth

and here is the information for the technology of geothermal energy:

-it's clean and sustainable

-resources of geothermal energy range from the shallow ground to hot water and hot rock found a few miles beneath the earth's surface, and down even deeper to the extremely high temperatures of molten rock called magma

-almost everywhere, the shallow ground or upper 10 feet of the earth's surface maintains a nearly constant temperature between 50° and 60°f (10° and 16°c)

-geothermal heat pumps can tap into this resource to heat and cool buildings

-a geothermal heat pump system consists of a heat pump, an air delivery system (ductwork), and a heat exchanger-a system of pipes buried in the shallow ground near the building

-in the winter, the heat pump removes heat from the heat exchanger and pumps it into the indoor air delivery system

-in the summer, the process is reversed, and the heat pump moves heat from the indoor air into the heat exchanger

-the heat removed from the indoor air during the summer can also be used to provide a free source of hot water

luster is not a good characteristic to use by itself because luster is the property of minerals that indicates how much the surface of a mineral reflects light. the luster of a mineral is affected by the brilliance of the light used to observe the mineral surface.
