Comment on Thinking questions for rates by The Math Maker

I like the last two examples which show the relationship between distance, time and speed in different ways. A rather strange thing is that I found that students struggle more with the third form than the second form and yet neither is really more complicated than the other. Perhaps it’s the way students are taught the formula, s=ut (s=distance,u=speed), and then have difficulty recognizing its other forms (apart from algebraic difficulty of changing the subject of the equation). Thanks again for the interesting post!

When I read this, you reminded me of a little problem I used to use with Physics students; indirectly related, the harmonic mean (although you can have a weighted harmonic mean). The simplest version; a person travels from A to B at 20 mi/h and immediately returns at 30 mi/h; what is the average speed for the total journey assuming that the time to turn around is negligible? You guessed it, just about every time I got the answer 25 mi/h! Thanks for the great posts.

This is very interesting. Would it be possible to build a simulation for this problem? the x% will be the variable. while the students could also change the other “variable” as sliders and I have a feeling it could be also represented graphically. What is so nice about GeoGebra that it provides such a strong visual connection between pictures, numbers, graphs, spreadsheets… Also the best thing is to teach students to DO the simulations because then THEY are doing the Math themselves.
