Correct Answer: 10 km, East
Solution : According to the instructions given, the diagram is as follows –
Here, A is the starting point and B is the finishing point and AB is the total distance from the starting point.
AC = 25 km; BC = ED = 15 km; CD = BE = 30 km
And, AB = AC – BC = 25 – 15 = 10 km
So, the distance between point B and point A is 10 and is in the East direction. Hence, the fourth option is correct.
