1.Jack is strolling along the bank of a 1-km wide River when the most beautiful girl materialises on the shore directly opposite him. Fearing she will disappear before he has a chance to establish face-to-face communication, he quickly devises a plan to reach the opposite shore in the shortest possible time. There is a rowboat breached on the shore right infront of him. He knows he can row at a speed of 6 km/h in still water and the current has a speed of 3 km/h. He must reach the opposite side of the river in the shortest time. His path includes a diagonal trip across the river followed by a sprint along the opposite shore to reach Jill. Jack has a standard sprinting speed of 10 km/h. What direction did he head his boat.(adsbygoogle = window.adsbygoogle || []).push({});

P.S Im still looking for number 2 on my other post. I thought I had the answer but it was wrong.
