    x - (1/3)x = 6 (2/3)x = 6 x = 9 it would take 9 hours for it to reach 6 o'clock

    12 + 1 would be a normal hour correct? but it loses 1/3 hour each time. 12 + (1 -1/3) is how the watch runs...

    12 + (1 -1/3)(x hours) = 18 (1 -1/3)(x hours) = 18-12 = 6 (2/3)(x hours) = 6 hours x = 6(3)/2 = 18/2 = 9 9 hours it ran slow then died. 12 + 9 = 9pm + 4hours = 1am
