    The time it will take me to wash 12 plates 45 seconds

    Step-by-step explanation:

    If i can wash 48 plates in 3 minutes, it means i can wash 1 plate in 3 minutes (60*3 seconds) divided by 48

    That is 180 seconds/48 = the time it will take me to wash 1 plate

    the time to wash 1 plate = 3.75 seconds

    Then the time it will take me to wash 12 plates = 12 times the time it takes me to wash 1 plate = 12*3.75 = 45 seconds

    I will therefore wash 12 plates in 45 seconds
