Using proportions, it is found that the dedicated link would take 5.72 hours, which is significantly less time than the USPS delivery, hence the link should be used.
A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.
Each TB has 1000 GB, hence:
20.6 terabytes = 20,600 Gigabytes.
You have available a 1 Gbps dedicated link for data transfer, hence the time it would take for the transfer through the dedicated link is:
20,600/1 = 20,600 seconds.
Each hour has 3600 seconds, hence the time in hours is:
20600/3600 = 5.72 hours.
The dedicated link would take 5.72 hours, which is significantly less time than the USPS delivery, hence the link should be used.
