An airplane travels 200 km/h through the air. If it heads directly against a 40- km/h wind, what is its speed relative to the ground?
take 40 away from 200
thanks. :) how can i illustrate the problem?
To determine the airplane's speed relative to the ground, we need to consider the effect of the wind. The airplane's speed through the air is 200 km/h, but the wind is blowing against it at a speed of 40 km/h.
To find the airplane's speed relative to the ground, we can subtract the speed of the wind from its speed through the air.
Speed of the airplane relative to the ground = Speed of the airplane in the air - Speed of the wind
In this case, it would be:
Speed of the airplane relative to the ground = 200 km/h - 40 km/h
Calculating the subtraction, we get:
Speed of the airplane relative to the ground = 160 km/h
Therefore, the airplane's speed relative to the ground is 160 km/h.
