Approximately how long would it take a telegraph signal to cross the united states from the east coast to the west coast? (teleg
castortr0y [4]

If the coast-to-coast distance is about 2900 miles, it will take about ...

... (2900 mi)/(186000 mi/s) ≈ 15.6 ms

for the signal to travel coast-to-coast at light speed.

_____

There are time delays due to the amplifiers and repeaters required in the path, and due to the fact that the signals don't actually travel at the speed of light in a wire.

A test of internet speed between Seattle and Washington, DC shows a round-trip time of about 87 ms when traffic is light. Modern communication channels tend to be faster than the telegraph (especially when measured in words per minute).

What are *TWO* measures introduced by the US and local governments to reduce the consumption of gas?
Alisiya [41]

Answer:

Two measures that have been introduced by the US and local governments to reduce the consumption of  gas are the introduction of light-rail and the use of carpool lanes.  

Explanation:

The introduction of light-rail will reduce the consumption of gas from personal vehicles and also reduce personal vehicle carbon emissions. One example is the Dallas Area Rapid Transit (DART) and Los Angeles has a system that combines light rail and heavy rail called Metro Rail. The use of carpool lanes will reduce the use of gas and help to reduce traffic congestion because there will be less cars on the road in high traffic areas where there is a large percentage of the population who commutes to and from work on freeways. Carpool lanes or High Capacity Vehicle (HCV) lanes are found in metropolitan areas like Washington DC.
