Answer:
t = 2000 ÷ 10 = 200 seconds
Time taken to reach end point t = 200 seconds
Step-by-step explanation:
Given;
Rate of inflow = 30 liters per second
Rate of draining = 20 liters per second
Rate of overall inflow = 30 - 20 liters per second = 10 liters per second.
Starting point = 10000 liters
End point = 12000 liters
Change in volume = 12000-10000 = 2000 liters
Time taken to reach end point t = change in volume ÷ rate of overall inflow
t = 2000 ÷ 10 = 200 seconds
Time taken to reach end point t = 200 seconds
Answer:
200 seconds
Step-by-step explanation:
If the income of water is 30 liters per second and the outcome is 20 liters per second, we have that the increase in water is:
30 - 20 = 10 liters per second
So, if the starting point is 10000 liters and the final point is 12000 liters, the increase in the amount of liters is:
12000 - 10000 = 2000 liters
If our net income is 10 liters per second, it will take 2000/10 = 200 seconds to get from the starting to the final point.
