Question

Assume a telephone signal travels through a cable at two-thirds the speed of light. How long does it take to get from New York City to Miami if the distance is approximately 1100 miles?

 

I know I multiply 2/3  ( 3x 10^8 m/s) . What do I do next?

Answer 1

Light travels at 186,282 miles per second

miles/(miles/sec) = seconds

 

1100/[(2/3)(186,282)] ≅ 8.05 X 10^-4 seconds or 0.000805 seconds
