QuestionEurrent Attempt in Progress
A village wishes to measure the quantity of water that is piped to a factory during a typical morning. A gauge on the water line gives the flow rate (in cubic meters per hour) at any instant. The flow rate is about $140 \mathrm{~m}^{3} / \mathrm{hr}$ at 6 am and increases steadily to about 280 $\mathrm{m}^{3} / \mathrm{hr}$ at 9 am . Using only this information, give your best estimate of the total volume of water used by the factory between 6 am and 9 am.
Best estimate = i $\square$ $\mathrm{m}^{3}$
