for a webapp I would like a 'speed' search field in which users could search by concrete speeds in kilometers per hour km/h, and at the same time they should have the possibility to make a less accurate search by choosing between 'slow. medium, or fast'. So the possible searchs in that field would be
- xxx km/h
where xxx is any number (e.g- 60 km/h, 200 km/h)
What's the best solution for that?
