$Version

9.0 for Mac OS X x86 (64-bit) (November 20, 2012)

Either use Mathematica recognized units

UnitConvert[Quantity[55,"Miles"/"Hours"],"Meters"/"Seconds"]

96800/3937 m/s

%//N

24.5872 m/s

%//InputForm

Quantity[24.58724917449835,
 "Meters"/"Seconds"]

Or use WolframAlpha to interpret the vernacular

WolframAlpha["convert 55 mi/hr to m/s",
{{"Result",1},"ComputableData"}]

24.59 m/s

%//InputForm

Quantity[24.59, "Meters"/
  "Seconds"]
