What is the speed of a plane that travels at a rate of 590 mph agaisnt a wind of r mph?
---------------
The airspeed of the plane is 590 mi/hr.
The groundspeed is 590-r mi/hr.

for every hour that the plan flies, it is traveling 590 miles.

for that same hour, the wind is traveling in the opposite direction for r miles.

that means that the wind is pushing the plane back r miles for every 590 miles is is going forward.

the net progress of the plane is therefore 590 - r miles per hour.
