Q

The capacity of a particular ballast pump is 200 gallons per minute. Approximately how long will it take to ballast a tank with 68.5 long tons of seawater?

🔍 Key Concepts

• Unit conversions between long tons, pounds, and gallons of seawater • Relationship: Time = Volume ÷ Pump rate (both in compatible units) • Approximate weight per gallon of seawater

💭 Think About

• First, convert 68.5 long tons into pounds, then into gallons of seawater using an approximate pounds-per-gallon value. What common value is used for seawater? • Once you have total gallons, how do you use the pump capacity (gallons per minute) to find the total time in minutes? • After you find minutes, how do you convert that time to hours, and which answer choice is closest to your result?

✅ Before You Answer

• Be sure you use 1 long ton = 2,240 lb, not the short ton value • Use a consistent approximate value for seawater density in lb/gal throughout your calculation • Confirm you convert minutes to hours correctly before comparing to the answer choices
