Lesson: Intermediate Problem Solving - 06

Estimating — Rates

[Page 6 of 27]

Our strategy of establishing a logical range for correct answers, then eliminating choices outside of that range, also works well on rate problems (and particularly well on combined-rate problems). Let's consider an example.


Steve gets on an elevator at the 11th floor of a building and rides up at a rate of 57 floors per minute. At the same time Joyce gets on an elevator on the 51st floor of the same building and rides down at a rate of 63 floors per minute. If they continue traveling at these rates, at which floor will their paths cross?
