I think you are mixing Megabits (Mb) and Megabytes (MB, notice the capital B) here.
Broadband line speed is told in megabits per second (Mbps or Mb/s), but download managers (including those built-in on every browser) tell the actual download speed in kilobytes and megabytes per second (KBps or KB/s, MBps or MB/s).
One byte = 8 bits, so for instance if you have a 10 Mbps broadband line, you theoretical maximum download speed is a little bit over 1.2 MBps, so it looks that your friend is getting downloads about as fast as possible, her theoretical maximum being about 1.33 MBps.
