What is the combined speed if a plane traveling at 500 km/hr has a tail wind of 50 km/hr?
Just 500 + 50 will give you the combined speed. a tail wind always adds, while a head wind slows you down.
To calculate the combined speed of a plane with a tailwind, you simply add the speed of the plane to the speed of the tailwind. In this case, the plane is traveling at 500 km/hr and has a tailwind of 50 km/hr.
So, to calculate the combined speed, you would add the plane's speed of 500 km/hr to the tailwind's speed of 50 km/hr:
Combined speed = plane's speed + tailwind's speed
= 500 km/hr + 50 km/hr
Adding these two speeds together, we get:
Combined speed = 550 km/hr
Therefore, the combined speed of the plane with a tailwind of 50 km/hr is 550 km/hr.
