Hi I need help with this thx A water tank fills through two pipes. Water flows through
one pipe at a rate of 25,000 gallons an hour and through
the other pipe at 45,000 gallons an hour. Water leaves the
system at a rate of 60,000 gallons an hour.

There are 3 of these tanks, and each tank holds 1 million
gallons. Each tank is half full. Water is entering and
leaving a tank at the maximum amounts. Determine the
number of hours, x, it will take to fill all 3 tanks.
