Difference between sthg*time & sthg/time

    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!
