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.

Granulated blast furnace slag is a glassy granular material that varies, depending on the chemical composition and method of production, from a coarse, popcornlike friable structure greater than 4.75 mm (No. 4 sieve) in diameter to dense, sand-size grains passing a 4.75 mm (No. 4) sieve.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).
