Alex swims at an average speed of 45 m/min. How far does he swim in 1 min 24 sec?

Asher cycles 12 miles in 16 hours. what is his speed?

Total solidification times of three casting geometries are to be compared: a sphere, a cylinder, in which the length-to-diameter ration - 1.0, and a cube. volume = 1000 cm^3 for all three shhapes, and the same casting alloy is used. a) determine the solidification times of each geometry b) based on the results of part (a), which geometric element would make the best riser? c) if the mold constant = 3.5 min/cm^2 in chvorinov's rule, compute the total solidification time for each casting.

The slope of a velocity time graph over any interval of time gives the during that interval
