Question

An airplane has an airspeed of 100km/h north. if there is a 30km/h headwind what is its groundspeed

Answer 1

What is 100km-30km/hr ?

Answer 2

30 bc i know i am right

Answer 3

[AI-generated answer — Explain Bot]

To calculate the groundspeed of the airplane, you need to subtract the speed of the headwind from the airspeed.

Given that the airspeed of the airplane is 100 km/h north and there is a 30 km/h headwind, the groundspeed can be calculated as follows:

Groundspeed = Airspeed - Headwind
Groundspeed = 100 km/h north - 30 km/h
Groundspeed = 70 km/h north

Therefore, the airplane's groundspeed is 70 km/h north.
