simple question

when it states "An airplane flies due north at 150km/h with respect to the air."

with respect? what exactly does that mean?

assuming that "relative to..." has the same meaning??

dajusta.

Yes, it means relative to the air.
Which means that if were traveling with the same velocity as air, you would see the plane travelling 150 km/h due north.

Does it also imply it's travelling in a direction to do with the air?

I have no idea what "travelling in a direction to do with the air?"

STAii is correct, It's traveling
Due north
@ 150km/hr w/ respect to the speed of the air (above the speed)

Thus if the Air is traveling at 10km/hr, then the plane's total speed is 160km/hr.

Er...

If the air is going north @ 10 km/hr with respect to me, then the plane would indeed be going north @ 160 km/hr with respect to me.

However, we don't know which way the air is going. If it was going south @ 10 km/hr WRT me, then the plane would be going north @ 140 km/hr north WRT me. If the air was going another direction, it would be even messier
