AI Thread Summary
The discussion clarifies the difference between multiplying and dividing physical units by time. Multiplication by time is often expressed with "for," indicating total distance or production over a set duration, such as "I walked for ten hours." In contrast, division by time uses "per," as seen in "miles per hour," which reflects a rate or speed. Examples include calculating earnings or production rates, where dividing by time gives a rate, while multiplying by time gives total output. Understanding these concepts helps clarify how time influences various physical measurements.

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!

I think it's easist first to watch a short vidio clip I find these videos very relaxing to watch .. I got to thinking is this being done in the most efficient way? The sand has to be suspended in the water to move it to the outlet ... The faster the water , the more turbulance and the sand stays suspended, so it seems to me the rule of thumb is the hose be aimed towards the outlet at all times .. Many times the workers hit the sand directly which will greatly reduce the water...
