Question

The ambelfield aquifer is estimated to hold 50 billion liters. Assuming no addition or depletion of water, for approximately how many days could water be pumped if 15 million litres were extracted each day?​

Answer 1

Divide,

$\dfrac{50\cdot10^{9}}{15\cdot10^6}=\dfrac{50}{15}\cdot10^3\approx3.33\cdot10^3\approx3333.3\mathrm{D}$

About 3333.3 days.

Hope this helps.
