Joy is filling her hot tub with two hoses in the backyard. One hose can fill the tub in three hours while a thinner hose takes seven hours. However, Joy forgot to close the drain, so while the tub is being filled it's also draining! If it takes four hours to drain the hot tub, how long will it take to fill the tub with both hoses running and the drain open?

The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.
