Answer:
3600 gallons of water was removed from the basement.
Step-by-step explanation:
Given:
Rate of each pump = 40 gallons/min
We need to find find the number of gallons of water removed from the basement.
Solution:
Now Given:
After half an hour, the one pump burns out.
Now we know that;
1 hour = 60 mins
hour =
Now for 30 mins both the pumps were working and removing the water.
So we can say that;
Water remove for first 30 mins =
Also Given:
the second pump finishes removing the water half an hour later.
So we can say that;
Water removed for next 30 mins =
Now we can say that;
Total water removed from the basement is equal to sum of Water remove for first 30 mins and Water removed for next 30 mins .
