Speed, distance, and time problems ask to solve for one of the three variables given certain information. In these problems, objects are moving at either constant speeds or average Alice's plane is twice as fast as Bob's plane. When Alice finishes the race, the distance between her and Carly is.M c Squared System Design Group, Inc. 323 - 901 West 3rd Street, North Vancouver, BC.

The discharge of the stream is . 1000 1000 square feet per second 1000 cubic feet per second. Engineers fix the stream so that its width and depth cannot increase. Perhaps they force the stream to flow through a concrete liner.
