Hi,

You can find this material helpful.
 
Formula to calculate time = total number of bits to be downloaded/data rate in bps = total number of bytes x8/data rate in bps.
 
a. V. 32
 
Here
 
Total data = 2,000,000 bits
 
Data rate = 9.6 kbps = 9600 bps
 
Hence
 
Time = (2,000,000 × 8) /9600 = 1668 s
 
b. V. 32bis
 
Total data = 2,000,000 bits
 
Data rate = 14.4 kbps = 14400 bps
 
Time = (2,000,000 × 8) / 14400= 1112 s
 
c. V. 90
 
Total data = 2,000,000 bits
 
Data rate = 56 kbps = 56000 bps
 
Time = (2,000,000 × 8) / 56000 = 286 s
 
d. Cable Modem
 
We can calculate time based on the assumption of 10 Mbps data rate which is usually used:
 
Total data = 2,000,000 bits
 
Data rate = 10 Mbps = 1000 kbps = 10,000,000 bps
 
Time = (2,000,000 × 8) / 10,000,000 = 1.6 s.
