Math Lesson

By: Mr. Wilson on December 18, 2006

Would anybody care to tell Dr. Fowler what's wrong with his answer to his math quiz in this morning's Journal Star (not online, as far as I can tell)?

Elisa swims laps in the pool. When she first started, she completed 10 laps in 25 minutes. Now she can finish 12 laps in 24 minutes. By how many minutes has she improved her lap time?

Dr. Fowler's answer? 0.5 seconds. Is it just me, or do Dr. Fowler's math skills on this problem resemble Verizon's?

This is why they taught us, back in Physics 211, never switch units without showing your work.

Yes, a number of people pointed out my error, as well as the notorious Verizon recording.
