They then spent the next 4 hours pumping milk at a rate of 2,880 gallons/hour from the storage tank into a milk tanker. For the next 7 hours, the workers added more milk into the storage tank, at a rate of 1,500 gallons per hour. How many gallons of milk were left in the storage tank? Your thoughts: <hau> Tambayata ita ce: A safiyar yau, ma'aikatan manomi Rita sun tattara galan 30,000 na madara kuma sun sanyaya shi a cikin tankin ajiya.
