Answer:

641 times

Step-by-step explanation:

Rate of transfer in 1989

2.4 kilobytes per second

Rate of transfer in a typical modem

1000 kilobyte per 0.65 seconds

Transfer per second for typical modem

1000/0.65=1538.461538  kilobyte per second

Comparing typical modem to 1989

[tex]\frac {1538.461538 kilobyte/s}{2.4 kilobyte/s}[/tex]

=641.025641  times faster

Rounding off, this is 641 times faster

Therefore, ans=641 times
