🔍 Key Concepts

• Relationship between speed, time, and distance: ( \text{Speed} = \frac{\text{Distance}}{\text{Time}} ) • How to find fuel consumption per hour from a known voyage segment • How changing speed (knots) affects total time and therefore fuel used

💭 Think About

• First, use the completed part of the voyage to find how many hours you have already steamed and how many tons of fuel were burned per hour at 21 knots. • Next, calculate how many hours it will take to cover the remaining distance at the new speed of 25 knots. • Finally, apply the fuel consumption rate (tons per hour) to the new steaming time to estimate the fuel needed from now to the next port.

✅ Before You Answer

• Be sure to convert distance to time using the correct speed each time: ( \text{Time (hours)} = \frac{\text{Distance (NM)}}{\text{Speed (knots)}} ). • Double-check that you are using fuel per hour, not fuel per mile, based on the original data. • After you compute the fuel needed for the remaining leg, compare your result to the choices and check if it is a reasonable change compared with the original 635 tons burned.
