Renaissance music Nova (see Medieval music), there could be either two or three of these for each breve (a double-whole note), which may be looked on as equivalent to the modern "measure," though it was itself a note value and a measure is not. The situation can be considered this way: it is the same as the rule by which in modern music a quarter-note may equal either two eighth-notes or three, which would be written as a "triplet." By the same reckoning, there could be two or three of the next smallest note, the "minim," (equivalent to the modern "half note")
Value of time can be examined. For example, if a traveler has a choice between a coach which takes six hours and costs £10, or a train which takes four hours and costs £30, we can deduce that if the traveler chooses the train, their value of time is £10 per hour or more (because they are willing to spend "at least" £20 to save two hours' travel time). The difficulty in narrowing down the "actual" value of time from a pair of choices means that hypothetical situations are generally used (the stated preference technique) to deduce values of time. The value of
