Answer» { See the ATTACHMENT for the PATH, travelled by the man } Drawing the path, we get a triangle ODE, which is a right-angled triangle whose BASE is OE = 3 km and height is DE = 4 km Therefore, the required distance of the man from its starting point is = OD = √(3² + 4²) km = √(9 + 16) km = √25 km = 5 km # |
