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 is a nonmetallic coproduct produced in the process. It consists primarily of silicates, aluminosilicates, and calcium-alumina-silicates. The molten slag, which absorbs much of the sulfur from the charge, comprises about 20 percent by mass of iron production.here can, however, be considerable variability in the physical properties of blast furnace slag, depending on the iron production process. For example, some recently produced ACBFS was reported to have a compacted unit weight as high as 1940 kg/m 3 (120 lb/ft 3).
