Discussion Overview

The discussion revolves around the conceptual differences between multiplying and dividing physical quantities by time. Participants seek clarification on how these operations apply in various contexts, using hypothetical examples to illustrate their points.

Discussion Character

  • Conceptual clarification
  • Exploratory

Main Points Raised

  • Some participants propose that dividing by time often relates to rates, such as "miles per hour," indicating a speed that decreases with increased time.
  • Others argue that multiplying by time relates to total quantities over a duration, exemplified by walking for a certain number of hours to cover a specific distance.
  • A hypothetical example involving a machine producing gummy bears is presented to illustrate the calculations of total production based on time and output rates.
  • One participant humorously illustrates the concept of division by time through a scenario involving hourly wages, highlighting the absurdity of receiving a low payment for a day's work.

Areas of Agreement / Disagreement

Participants generally agree on the basic principles of how multiplication and division by time function in different contexts, but the discussion remains exploratory without a definitive consensus on all nuances.

Contextual Notes

Some examples provided are hypothetical and may not cover all possible interpretations of multiplying or dividing by time. The discussion reflects varying levels of understanding and humor, which may influence the clarity of the concepts presented.

Who May Find This Useful

Individuals interested in understanding the application of time in physical calculations, particularly in contexts involving rates and total quantities, may find this discussion beneficial.

Difference between"sthg*time"&"sthg/time"

What's the difference between "something" multiplied by time and "something" divided by time ? Isn't everything done through an interval of time ? I'd appreciate it if you gave me some examples , any example even if its gummy bears /time , I just want to know how on Earth and when do I multiply physical units with time , thanks a million in advance !

Divided by time: You'll often see the word "per", as in "miles per hour"; if it takes ten times as many hours my speed was one-tenth as great as if it took one hour.

Multiplied by time: You'll often see the word "for", as in "I walked for ten hours and covered ten times the distance that I would if I had walked for one hour".

You can do this with a hypothetical machine that produces X GummiBears in Y hours and operates for Z hours :smile: - when you calculate the total production you'll be dividing by Y and multiplying by X.

Hi, suppose you went to work for $10 an hour and after 10 hours work your boss gave you $1. That's 10 dollars divided by 10 hours, right!

What, you want $100? Get outta here!

Then my boss would be a fraud , how am I supposed to support my family with 1 $ a day ? Is this the 16th century :P ,but I get it . Thanks a lot , Mr. Sarcastic interpreter >v>
