Learning networking - help with sample question

hi,

I'm presently learning networking and have this question that I'm not sure about. Can someone please tell me how to answer it?

Question:
In Ethernet bus transmission, sender needs to monitor the line for collision signal after sending message. If the length of backbone is 500 meters and the transmission speed is 250 meters per second, how many seconds must the sender monitor the line for collision signal?

thnx

250 meters/second? You must have the world's slowest ethernet

Oh yeah, 500m is out of spec for the maximum length of an ethernet 10bt cable segment.
