SUMMARY
Pierre's rowing problem involves calculating the angle at which he must head to row directly across a river while accounting for the current. Given that his rowing speed is 10 km/h and the river's current is 6 km/h, the angle can be determined using vector addition. The equation Vbg = Vbw + Vwg is essential, where Vbg represents the boat's velocity relative to the ground, Vbw is the boat's velocity relative to the water, and Vwg is the water's velocity relative to the ground. The solution requires applying trigonometric functions to find the correct heading angle.
