Answer:
a. (210^6)((210^7)/(2.510^8)) = 1.610^5 bits or 160,000 bits
b. 1.6*10^5 bits or 160,000 bits
c. Bandwidth delay product of link is maximum number of bits that can be in the link
d. Width of bit = Length of link / bandwidth-delay product so 1 bit is 125 meters long. Yes, this is longer than a football field.
e. Width of bit = s/R
Hope this helps :)
