Question 56
A signal travels 6000 km at 2$\times 10^8 m/s$. What is the propagation delay?
Detailed Solution
$T_p = 6\times 10^6/(2\times 10^8) = 0.03 s = 30 ms.$

Question 57
A 1500-byte packet crosses a 10 Mbps link. What is its transmission delay?
Detailed Solution
$1500 bytes = 12,000 bits; 12,000/10^7 = 1.2 ms.$

Question 58
A link has rate 50 Mbps and one-way propagation delay 10 ms. What is its one-way BDP?
Detailed Solution
$BDP = 50\times 10^6 \times 0.01 = 500,000 bits.$
