🔍 Key Concepts

• Relationship between gallons and cubic feet of water, and from cubic feet to long tons (2240 lb)** • How to use the pump’s capacity (gpm) and time (minutes) to find total volume pumped • Converting between weight (tons) and volume (gallons) using sea water density

💭 Think About

• First, calculate how many gallons the pump moves in one hour, starting from 200 gallons per minute • Think about how to convert that many gallons of sea water into long tons using a consistent set of units • Compare the weight pumped out to the original 300 long tons to find how much must still be in the tank

✅ Before You Answer

• Be sure you are using minutes to hours correctly (1 hour = 60 minutes) • Confirm the conversion from gallons of sea water to pounds, then from pounds to long tons (2240 lb) • Check that your final answer is less than the original 300 long tons and matches one of the multiple-choice options
