Suppose an Ethernet network is using a 500m coaxial cable, running at 100 Mb/s, and the propagation speed is 5 ns/m.

Suppose an Ethernet network is using a 500m coaxial cable, running at 100 Mb/s, and the propagation speed is 5 ns/m. In addition, the receiver for the collision detection needs to receive a minimum of 8 bytes which have collided to declare a collision occurred (to compare what it's transmitting to what it's receiving).
