Speed or velocity can be expressed as the distance divided by time.
0.0075 is a number. It does not have mass, or length, or volume of time. It cannot be expressed as a centimetre.
The speed of an object is expressed as a distance traveled per unit of time. When referring to an "object," the formula is v = d/t, where v = speed (meters/second), d = distance traveled (meters), and t = time (second) When referring to travelling systems such as cars, bicycles, or aircraft, it is more appropriate to use a similar formula except that distance traveled is expressed in kilometers or miles and time is expressed in hours.
615 is a time of day: it is not, and cannot be expressed, as a fraction of an hour.
distance
Speed or velocity can be expressed as the distance divided by time.
-- The distance that light travels in some amount of time is expressed in units of distance. -- The time that it takes light to cover some amount of distance is expressed in units of time. -- The speed of light is expressed in units of speed . . . distance/time

The themes and concerns expressed were all of the social and economic issues that were going on at a certain given time. This is typical no matter the time or era.
Times in English are expressed by the contraction o'clock, which means "of the clock" or "on the clock".

Total distance divided by total time.
Velocity
This is called codominance. In codominance, both alleles are fully expressed in the phenotype of the individual.
The number of heartbeats per unit of time,usually expressed as beats per minute. The number of heartbeats per unit of time,usually expressed as beats per minute.
It depends on the context. If the two quantities being compared (numerator and denominator) are of the same kind then the rate CAN be expressed as a percentage. For example, both are money and the rate of interest is usually expressed as a percentage. However, the word "rate" is often used for comparisons over time. For example, speed is the rate of change of location (or distance) over time. Here the two measures - distance and time - are different and so the answer cannot be expressed as a percentage.
