Re "Common Core stumps parents, children alike" (Page A1, June 30): I am pleased to see that math is being emphasized in Common Core testing. At the same time, there is nothing to be gained by referring to pace in the middle school example as "minutes per mile."
I was always taught that pace (just another name for velocity) was defined as distance divided by time. To refer to pace as minutes per mile is unnecessarily confusing, since pace is not defined as time divided by distance.
Rather than introduce a bogus definition, the test writers could simply have have asked a simple question: How many minutes does it take the bird to fly one mile? Math is hard enough for many students without unnecessarily complicating it. -- Michael Eberhard, Folsom
