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.

Blast-Furnace Slag ï¬ Blast furnace slag is a by-product of pig iron manufacture. When quenched rapidly with water or air to a glassy state and finely ground, it develops the property of latent hydraulicity. ï¬ Blast furnace slag has chemical component similar to that of Portland cement.
