Explanation / Answer

4. Answer E: Since the ground water flow rate=0.4m/day

which means that the contaminated water will flow 0.4m in=1 day

We know that the total distance between the Otis air base and Falmouth city=5 km

So the contaminated water will cover 5 km or 5000m distance in=1/0.4*5000

=12500 days

Now we need to convert the days into the years so 12500/365=34.2 years

Approximately after 34 years the waste will start showing up in wells of Falmouth city.
