A nanosecond is 10 Superscript negative 9 second. Modern computers can perform on the order of one operation every nanosecond. Approximately how many feet does an electrical signal moving at the speed of light travel in a computer in 8 nanoseconds?

Answer:

The speed of light is approximately 3 x 10^8 m/s so multiplying by 8 nanoseconds will give a distance of 2.4 meters or in feet, approximately 7.9 feet.

1 foot = 0.3048 meter
