Concept explainers
(a)
Interpretation:
To determine the proportionality in mathematical form is to be stated for the given distance, d, that traveled at an average speed “s” is directly proportional to the time (t).
Concept introduction:
The term measurement defines seven fundamental units’ kilogram, meter, candela, ampere, kelvin and mole. The metric system is a decimal system of the measurement based on the units for the length, meter, the mass, the kilogram. It exists in several variations with different choices of the basic units. In common, U.S units are most similar to imperial systems. The distance, traveled by a moving substance with an average speed “s”, is directly proportional to the time, t. In this case, speed is denoted as proportionality constant. It can be measured in feet per second, kilometers per hour or any other mode of distance per unit time.
(b)
Interpretation:
The value and units of the proportionality constant is to be stated.
