Answer:
15ms
Explanation:
The propagation delay of sending data across the link between Host A and the router is 10ms at 1Mbps.
A 1500 byte package is equivalent to 1.5Mb, so the transmitting of this data would take;
1.5Mb of the data transmits at = 1 1/2 seconds
with a delay of => 10ms + (10ms/2)
= 10 + 5 = 15ms.
