Question

Find the ground speed of an airplane traveling into a 20 mph headwind with an air speed of 480 mph. Use the formula g = a − h, where g is the ground speed, a is the air speed, and h is the speed of the headwind

Answer 1

Step-by-step explanation:

he speed of the aeroplane 400km/h

The speed of the wind is 200km/h

So the aeroplane and the wind make a angle=θ to each other,

Thus the resultant velocity,
