Aviation Logistics: Calculating Ground Speed with Wind Currents
An aviation logistics firm is training dispatchers to account for wind when calculating flight paths. The plane's airspeed (speed in still air) is represented by , and the wind speed is represented by . To ensure accurate arrival times, the dispatcher must remember the specific formulas used to determine the plane's actual ground speed.
Based on the standard models for uniform motion with currents, identify the correct algebraic expressions for the plane's ground speed in the following two scenarios:
- The plane is flying with a tailwind (the wind is blowing in the same direction the plane is moving).
- The plane is flying against a headwind (the wind is blowing in the opposite direction the plane is moving).

A logistics manager is calculating the delivery schedule for a cargo boat. If 'b' represents the boat's speed in still water and 'c' represents the speed of the river's current, which expression represents the boat's actual speed when it is traveling upstream (against the current)?
A logistics coordinator for a maritime transport firm needs to account for river currents when scheduling barge deliveries. If 'b' represents the boat speed in still water and 'c' represents the speed of the river current, match the travel scenario to the correct expression for the effective speed.
When a logistics coordinator calculates the speed of a barge traveling upstream against a river current, the effective speed is determined by subtracting the current's speed from the barge's speed in still water.
Defining Variables for Current-Affected Motion
A logistics coordinator is analyzing how river currents affect the delivery speed of a transport barge. Rank the following scenarios in order from the fastest actual speed (at the top) to the slowest actual speed (at the bottom), assuming the barge's speed in still water () and the current's speed () are both constant and greater than zero.
A logistics analyst for a maritime transport company is calculating the delivery time for a cargo barge. If the barge's speed in still water is represented by and the speed of the river current is represented by , the expression used to represent the barge's actual speed when traveling downstream (with the current) is ____.
