I would imagine there's some overhead in processing a ton of file pointers to determine where the next chunk of a badly fragmented file is, as opposed to having a file stored in one continuous chain. Would that account for the difference? I have no idea.

The actual read operation(s) might not take much longer, but the host turnaround time will certainly affect things.

Optimized disk:
single read operation of N blocks

Fragmented disk:
read operation of N1 blocks
(host turnaround time 1)
read operation of N2 blocks
(host turnaround time 2)
...
where N1 + N2 + ... = N

Note that if the hardware implements read gather/write scatter operations and the O/S supports them, this may mitigate much of the host overhead due to fragmentation. I know that eMMC has such operations, and I assume that most other current protocols do, too.
Freedom is the freedom to say that two plus two make four. If that is granted, all else follows.
