a radio wave travels 186,000 miles per second. how many kilometers will the wave travel in one microsecond?
186000miles/second*1second/10^6microseconds * 1.62km/mile
To convert miles to kilometers, we can use the conversion factor that 1 mile is approximately equal to 1.609 kilometers.
Since we know that the radio wave travels at a speed of 186,000 miles per second, we need to calculate how far it will travel in one microsecond (which is one millionth of a second).
To find the distance in kilometers, we'll follow these steps:
Step 1: Convert miles to kilometers:
186,000 miles * 1.609 kilometers = 298,674 kilometers
Step 2: Convert seconds to microseconds:
1 second = 1,000,000 microseconds
Step 3: Divide the distance in kilometers by the time in microseconds:
298,674 kilometers / 1,000,000 microseconds = 0.298674 kilometers
Therefore, the radio wave will travel approximately 0.298674 kilometers in one microsecond.
