Well...
The time response is the correct answer for "How much time did you spend on your bike?"
It's also valuable if you are trying to document physical efforts as part of a training regime, because (among other things) it
allows you to count hours spent on the trainer.
But the time response is a red herring if the question is "How many miles did you ride?"
There's no such thing as Trainer Miles (sic) because miles is a unit of distance, and a trainer covers no distance no matter how many hours you sit on the thing spinning furiously.
