body: <p>Question from a networking class:</p>
  
  <p>"In a csma/cd lan of 2 km running at 100 megabits per second, what would be the minimum frame size to hear all collisions?"</p>
  
  <p>Looked all over and can't find info anywhere on how to do this. Is there a formula for this problem? Thanks for any help.</p>
