I got the answer as 888.88. Looking at these comments, I got that I needed to divide it by 2... I understood the calculations, but I just can't wrap my head around this line

Up to what distance (in meters) does the dog have the higher data rate than 100Mbps Ethernet?

444.44m would be the maximum distance the dog could go bring the pen drive. But what does that have to do with the dog having "higher data rate"? Lol. This might be a silly doubt, I realise, but can someone please help me get this line?
