A Dash 8 configured for landing will be doing something like 120 knots, so about 2.5 minutes to fly a 5 mile final. Of course they may have a 20 knot headwind in which case 3 minutes might be closer to the mark.

It all depends on your box. There's no point blindly reciting the numbers on the box if your box gives ETAs based on
current ground speed. I have a method for giving a Foxtrot time based on our SOPs (i.e, approach speed profile) and the box's time for India, it's usually right to within 30 seconds.
