John is filling his bathtub but he forgot to put the plug in. If the bathtub can accommodate a maximum volume of water of 0.350 m3 before water overflows and the tap is flowing at 79.2 L/hr and the drain is running at 19,200 cm3/hr, how long will it take to fill the tub to bath level? Assuming John shuts off the water when the tub is full and does not flood the house, how much water (in kg) will be wasted? Assume the density of water is 1,000 kg/m3
