🔍 Key Concepts

• Relationship between speed through the water and speed over the ground in a following or opposing current • How to add or subtract current from vessel speed depending on current direction • Unit consistency: both speeds given in mph so no conversion needed

💭 Think About

• Is the current helping you (pushing from behind) or opposing you (coming from ahead) as you pass under the bridge? • In that situation, should the speed over the ground be greater than or less than the speed you are making through the water? • Which math operation (addition or subtraction) correctly represents the effect of that current on your vessel’s progress over the bottom?

✅ Before You Answer

• Confirm which way the current is flowing relative to your course before deciding to add or subtract • Check that you are using speed through the water (9 mph) and current speed (3.5 mph) in the same units • After you calculate, verify that your answer is reasonable: does it match what you expect for a vessel being helped or hindered by the current?
