    Answer:

    4 minutes

    Step-by-step explanation:

    Let the time taken for them to have the same number of strawberries be x minutes.

    Initially

    Ruby: 10 strawberries

    Sapphire: 30 strawberries

    After x minutes

    Ruby: (10 +3x) strawberries

    Sapphire: (30 -2x) strawberries

    Since we let x minutes be the amount of time that has passed when they have the same amount of strawberries,

    10 +3x= 30 -2x

    Bring all x terms to one side, constant to the other:

    3x +2x= 30 -10

    Simplify:

    5x= 20

    Divide both sides by 5:

    x= 20 ÷5

    x= 4

    ∴ It will take 4 minutes.
