Tailwind
A wind current blowing in the same direction as an airplane is flying is called a tailwind. This wind assists the airplane, meaning its actual ground speed is increased. For instance, if an airplane's speed in still air is and the speed of the wind is , the effective rate of speed with a tailwind is .

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.
