Problem 1 : 15 (9, 2, 2, 2) points You have trained your dog, Bernie, to carry twenty 64Gbytes USBs instead of a flask of wine. You consider it an emergency when your disk fills up. The dog can travel to your side, wherever you may be, at 25 km/hour. For what range of distances does Bernie have a higher data rate than a transmission line whose data rate (excluding overhead) is 1Gbps? How does your answer change if (i) Bernies speed is halved; (ii) each USBs capacity is doubled; (iii) the data rate of the transmission line is halved.
