Question 624221: Suppose that water is pumped into an initially empty tank and the rate of water flow into the tank at time t (in seconds) is 50-t liters (L) per second. How much water flows into the tank during the first 30 seconds?

You can put this solution on YOUR website!
The rate of flow is +50t+ liters/sec
( liters/sec ) x ( sec ) = liters
After +t+ seconds, there are +50t%5E2+
liters in the tank
After 30 seconds,
+50t%5E2+=+50%2A30%5E2+
+50t%5E2+=+45000+
After 30 sec, there is 45,000 liters in the tank
