We define speed as distance divided by time. Distance is directly proportional to Velocity when time is constant. Speed, distance, and time problems ask us to solve for one of the three variables given certain information. In these problems, we deal with objects moving at either constant speeds or average speeds.e define speed as distance divided by time.

Definition. Waste content of metal ores that floats on the surface during the process of extracting or refining metal. Containing mainly silicates, sulfates, and phosphates of calcium, slag is used principally in road building and concrete admixtures.Also called tailing.aste content of metal ores that floats on the surface during the process of extracting or refining metal.

Slag cement (also called ground granulated blast furnace slag) is a hydraulic cement produced during the reduction of iron ore to iron in a blast furnace. Molten slag is tapped from a blast furnace, rapidly quenched with water (granulated), dried and ground to a fine powder.lag cement is most widely used in concrete, either as a separate cementitious component or as part of a blended cement. It works synergistically with portland cement to increase strength, reduce permeability, improve resistance to chemical attack and inhibit rebar corrosion.
