Question

A barrel had 20 liters of water. Water leaked out from the barrel at a constant rate. After 24 hours, 14 liters of water was left in the tank. How many liters of water leaked out per hour?

Answer 1

Let K equal the constant flow rate.
Let t equal time

So the equation is\[20-K(t)=14\]
Since t = 24 hours
\[20-K(24)=14\]
Solve for K

K = .25 liters per hour
