Suppose Host A wants to send a large file to Host B. The path from Host A to Host B has two links, of rates R1 = 250 kbps, R2 = 500kbps.

Suppose the file is 500.000 bytes. Dividing the file size by the throughput, roughly how long will it take to transfer the file to Host B? Ignore queuing delay , propagation delay, and processing delay.

a. 2000s

b.250s

C.1600s

D.16s
