At 6:00 AM:
there were 400 gallons of water in the pool
so,
At 11:00 AM:
there were 2400 gallons of water in the pool
so,
now, we can find time between
t=11-6=5 hours
now, we can use formula
rate of change of water in pool is
=( change in water quantity)/( total time)
so, we get
now, we can plug values
So,
The rate of change of water in the pool is 400 gallons / hour
