Reserve tank 1 is capable of holding z gallons of water. water is pumped into tank 1, which starts off empty, at a rate of x gallons per minute. tank 1 simultaneously leaks water at a rate of y gallons per minute (where x > y). the water that leaks out of tank 1 drips into tank 2, which also starts out empty. if the total capacity of tank 2 is twice the number of gallons of water actually existing in tank 1 after one minute, does tank 1 fill up before tank 2?
