I often use rate, speed, velocity, distance and time. In a mathematics textbook for perspective elementary and middle school teachers that I helped author we had questions on distance, time and rate in a section titled Ratio and Proportion. If you or someone else has other suggestions for classifying the type of problem you quote I would be very happy to hear them. Harley
