A radio wave travels 186,000 miles per second. How many kilometers will the wave travel in one microsecond? (1 mile = 1.61 km)
Komok [63]
1) 1 second = 1000000 microseconds

2) 186000 / 1.61 = 115527.9503 Km

3) We use the equation:
Speed = distance / time

4) rearrange for distance by multiplying both sides by time to get;

Distance = speed x time


5) plug in the values:

Distance = 115527.9503 x 0.000001
= 0.1155279503 Km
