Suppose the length of a 10Base5 cable is $2500$ m. If the speed of propagation in a thick coaxial cable is $200,000,000$ m/s, how long does it take for a bit to travel from the beginning to the end of the network? Assume that there is a $10$ μs delay in the equipment due to repeaters and there is a repeater for every $500$ meters?

  1. $26.5$ micro seconds
  2. $52.5$ microseconds
  3. $47.5$ micro seconds
  4. $37.5$ micro seconds

The answer is 52.5 microseconds 

40  microseconds  due to the router and 12.5 due to the propagation delay
