Miguel's irrigation tank for his large garden held 45.5 gallons before he began to fill it at a rate of 17 gallons per minute. Before he started watering the plants in his garden, Miguel's friend Alejandro checked his irrigation tank and found it contained 425 gallons. If Alejandro is irrigating his plants at rate of 11.5 gallons per minute, how much water will be in each tank when both tanks have the same amount of water?
