What is the distance (in km) between his starting point and end point?

Consider the solution for the first question of this set.
∴ Effective horizontal distance travelled = 6 + 3 = 9 km
∴ Effective vertical distance travelled = 8 + 4 = 12 km
∴ Distance between starting and end point = 92+122 = 15 kms.
Hence, option (d).
