Answer:

360 msec

Explanation:

Data provided in the question:

Distance between the two hosts = 15,000 kilometer

= 1.5 × 10⁷ m    [ ∵ 1 km = 1000 m ]

Transmission rate, R = 5 Mbps = 5 × 10⁶ bits per second

Propagation speed over the link = 2.5 × 10⁸ meters/sec

Size of file to be sent = 1,500,000 bit

Now,

Propagation delay (dprop)

= Distance ÷ Speed

= ( 1.5 × 10⁷ ) ÷ (2.5 × 10⁸)

= 0.06 sec

= 60 msec           [ ∵ 1 sec = 1000 millisecond ]

Transmission delay (dtrans)

= Size of file ÷ Rate of transmission

= 1500000 ÷ ( 5 × 10⁶ )

= 0.3 sec

= 300 msec

Therefore,

Time required for transmitting the file

= Propagation delay + Transmission delay

= 60 msec + 300 msec

= 360 msec
