It means your Download speed is 5800.47 Kilobits per sec = 5.66 Megabit per sec. (1 Mega = 1024 kilo, that is why the 2 numbers are not exactly the same.)
Your Upload speed is 725.06 kilo bits per sec.
Both speeds are very good for most purposes. That is very typical for most DSL or FiOS connection. Cable connections are usually much slower due to sharing the bandwidth with your neighbors.
The reason why the download speed is faster than the upload speed is because most DSL is actually aDSL, which means it is asymmetrical for upload/download. That is because most people download info from websites more so than uploading info back to the world, so the network carrier optimizes the performance by allocating more bandwidth to downloads than uploads. Otherwise, if the speeds are symmetrical, your download speed will be cut in half, even though your upload speed will go up, but if you are not using it, it is wasting it.
Total test time is 14.123 Seconds means it takes 14 sec to complete the round-trip testing between upload and downloads.
Speedtest X HD does not test for latency. Latency is the delay time between the time the signal is sent from the website to where you are. The latency usually increases with physical distance between 2 points, but other factors also affect the latency, such as the intermediate points that the signal has to hop through before it gets to your iPad, and the processing time it takes for those network equipment to relay the signal. That includes your own wireless router's processing time, and any other routers in transit, and also the software processing speed too.
