    Answer:

    It will take 5 minutes for both faucets together to fill the water cooler

    Step-by-step explanation:

    I’m kinda just guessing but I do have a reasonable explanation

    So the average time it takes for the faucets INDIVIDUALLY to fill the water cooler is 10 minutes

    But since both faucets are filling them TOGETHER, it should take half the time

    And half of 10 is 5

    So it should take 5 minutes for both faucets together to fill the water cooler

    If that makes sense

    Answer:

    A cold water tap takes 3 minutes to fill the bath. A hot water tap takes 2 minutes to fill the bath. How long does it take to fill the bath when both taps are open at the same time?

    It is easiest just to let the bath be a given size.

    My little bath will be 12 litres

    cold water  4L/min          hot water = 6L/min      

    together 10L/1 min

    10*(12/10) L per  1*(12/10) minutes

    12L per 1.2min

    12L per 1min and 12sec

    It will take 1 minute and 12 seconds to fill the bath.
