Answer:
It will be around 146,27 min since the pump is turned on until the deck is clear of the water.
Explanation:
When the leak is discovered and the pump is turned on, the lower deck is already submerged and the leak is not fixed; then, in order to have the deck clear of water, the bilge pump has to remove the <em>accumulated water </em>(
) and the <em>water that is taking on</em> (
) through the leak. We can represent this mathematically as follow:
<em>Equation 1</em>
Where:
: is the accumulated water when the leak was discovered
: is the takes on rate through the leak = 57.5 gal/min
: is the removing rate of the bilge pump = 73.8 gal/min
t= is the time since the pump is turned on until the deck is clear of water.
To calculate the accumulated water (), we will model the lower deck as a flat-bottomed container with a bottom surface area of 510 
and straight vertical sides. Knowing that the level submerged is 7.5 inches, and performing the corresponding unit conversions, we obtain:
= bottom surface area * lever submerged
<em>Equation 2</em>
Solving equation 1 for time (t), and replacing the value obtained in equation 2, we get:
146,27 min

Bottom-up Estimation
Explanation:
Bottom-up estimation is a type of project cost estimation that considers the cost of individual project activities and finally sums them up or finds the aggregates. The summation gives an idea of what the entire project will cost.
This is an effective way of estimating the cost of a project as it evaluates the costs on a wholistic basis. It also considers the tiniest details during the estimation process. The process moves from the simpler details to the more complicated details.
