Gertrude,
Without wishing to get into a detailed discourse about approach speeds, I would ask you to accept that at the busier airfields/airports the vast majority of approaching aircraft will be able to achieve 160kts to 4nm. Where we are dealing with the integration of MEP/SEP types with significantly slower approach speeds at all stages of the approach I might suggest that most, but perhaps not all, controllers will make due allowance for the performance of those types. If you are more comfortable flying the ILS at 85kts tell the controller and he/she will work the rest around you. Aviate, navigate, but don't forget to communicate - its what CRM is all about.
