A construction company recently built a thirty-story building on a lakefront in China. Architects and engineers designed the building to withstand a magnitude 9.0 earthquake. The most impressive thing about this building, though, is that it took only 360 hours to build.

Question

How many days did it take to construct the building?
10 days
15 days
20 days
25 days

Answer 1

To find out how many days it took to construct the building, you divide the total hours by the number of hours in a day.

There are 24 hours in a day, so:

\[ \text{Days} = \frac{\text{Total Hours}}{24} = \frac{360 \text{ hours}}{24 \text{ hours/day}} = 15 \text{ days} \]

So, it took 15 days to construct the building.
