SUMMARY
The discussion focuses on calculating the ground velocity of a light plane traveling at 175 km/h on a heading of 8° east of north, affected by a 40 km/h wind from 80° east of north. The correct ground velocity is determined to be 167 km/h, contrasting with an incorrect calculation of 191 km/h. The error arose from misapplying the cosine law and incorrectly drawing the velocity triangle, leading to confusion in vector subtraction.
