A pool contains 300L of water. It empties at a rate of 6.4L/min. Write an equation to determine how long it will be until the pool contains only 60L of water.
v = 6.4 L/min is the rate of emptying the pool
Since the pool needs to go from 300 L to 60 L, this means that the amount of the water that will go out of the pool is 300 - 60 = 240 L.
t = the time needed until the pool contains 60 L of water only
v = 240/t
we need to solve:
240/t = 6.4

t = 37.5 min
After 30.5 minutes the pool will have only 60 L of water.
