🔍 Key Concepts

• Speed through the water vs. speed over the ground • How current adds to or subtracts from your boat’s speed • Converting knots vs. mph (and noticing what units are already given)

💭 Think About

• Ask yourself: Is the vessel’s speed through the water given anywhere, or are you only told the speed of the current? What does that imply? • Think about what speed over the ground means. Can you find it if you don’t know how fast the boat itself is moving through the water? • Look at the choices. Do any of them match the current speed, or are they all different? What might that be telling you?

✅ Before You Answer

• Be clear on the difference between current speed and vessel speed. • Confirm whether you have enough information to calculate a single numeric speed over the ground. • Check that you’re not accidentally treating the current as if it were the boat’s own speed.
