How Do I estimate the minimum and maximum time for the transmission of an ethernet frame. Plus How do I estimate the maximum numbers of bits that will be transmitted before a collision will be detected. the maximum segment length is 500 m and the electrical signal propagates at half the speed of light. how will i be able to use ethernet frame format for the calculation and show all the steps used for the calculations.

Um, wow.
Sounds like you are studying some (comparitably) ancient technology, friend.
This is non-sequiter. In a collision domain, the wire is yours to use until some other traffic tries to send a packet at the exact same time you do. In a modern, switched network there are no collisions.
Excuse me? 500 METERS?! What are you running, thickwire? <shudder> Abandon all hope, ye who enter here...
Man, that's some crappy cable. You can easily achieve propagation velociries of .85 or .9.

The Speed of light in Fiber is close to 67% of the speed of light in a vacuum. Copper is a little faster, near 70%
Hardly anyone uses any other media.
I tried to remain child-like, all I acheived was childish.

Minimum and maximum time would be dependent of the ethernet speed (10 meg, 100 meg, 1 gig, and 10 gig are the common speeds) and the length of a packet: 64 bytes to 9180 bytes, with a normal upper limit of 1518 bytes.
500m is either thicknet or fiber, not UTP, the 1/2 speed of light suggests fiber.
In a switched, full duplex network, (and they all should be) there simply are no collisions, although some times buffer overflows are listed as collisions. Any collision in full duplex is a topology error.
