Answer:
It just means "5-n"
Step-by-step explanation:
There's really nothing to it. It's just an expression, it doesn't 'mean' anything.
Anything smaller than 11.46. Decimal and whole number wise.
This is because it says Dan’s time was faster, meaning he took less time then Jake, thus making it so the time has to be smaller than 11.46.
Hope this helps!
