Could you please check my work, I am not too sure what do.
An airplane that flies at 100 km/h with a 10 km/h tailwind travels at 110 km/h relative to the ground. If it instead flies into a 10 km/h headwind, its groundspeed is :
110 km/h /2= 55 km/h
No. Traveling with the wind is 110 + wind speed.
Traveling against the wind is 110 - wind speed.
