Answer:
The ground speed of the plane is 513.6 km/hr.
The direction is 46.59°
Step-by-step explanation:
Given that,
Air speed of plane = 500 kph
Wind speed = 60 kph
The velocity of plane is

Put the value into the formula


The velocity of wind is

Put the value into the formula


We need to calculate the ground speed of plane




The ground speed is


We need to calculate the direction
Using formula of direction



Hence, The ground speed of the plane is 513.6 km/hr.
The direction is 46.59°
