Speed is a quantity that is measured in meters per second.
The previous answer, velocity, is technically incorrect.
Velocity is a vector, which consists of a magnitude and a direction.
Example: 10 meters per second northwest.
Speed, however, is a scalar, and consists solely of a magnitude.
Example: 10 meters per second.

Why are the units for acceleration meters per second?
Acceleration is not measured in meters/second. Meters/second is a unit of speed. Since acceleration is defined as change of speed divided by time, the units are meters/second/second, usually written as meters/second2.
Diffrent SI units are combined to obtain a?
Yes, acleration is the change in meters per second per second. So meters and seconds (twice).
Why is acceleration often expressed with units of meters per second squared?
Because if speed is measured in meters per second (m/s) and time is measured in seconds, the SI unit of acceleration is meters per second per second (m/s2). ^_^
He units of meters per second squared is a unit of?
Rate of change of speed. It can be the units for acceleration but need not be.
What quantity is calculated as the inverse of speed?
If speed is calculated in meters per second, the invers (reciprocal, actually) would be seconds per meter. I don't believe there is a special name for that. Some of the more commonly-used units have special names, like "Newton" for force, but not every unit has its own name. For example, square meters are just called square meters, and the units for speed (meters per second) and acceleration (meters per second square) are called just that, and don't have any special names.If speed is calculated in meters per second, the invers (reciprocal, actually) would be seconds per meter.
