Let us write the correct question as it has mistakes.
Mary travels 7 km towards the East and then travels 25 km towards her right. She then travels 10 km to the left and then travels 6 km towards her right. After this she travels 3 km towards the West and then stops. How far is she from starting point in the Southern direction, in kilometers?
(a) 29 km
(b) 10 km
(c) 31 km
(d) 28 km
Explanation:
AB = 7 km towards the East
BC = 25 km towards her right (South)
CD = 10 km to the left (East)
DE = 6 km towards her right (South)
EF = 3 km towards west
[You can refer figure attached]
The starting point is A
The ending point is F
From the figure, we can say that,
DE = CG = 6 km (Lines are parallel)
AH = BG (Lines are parallel)
AH = BC + CG
AH = (25 + 6) km
AH = 31 km
Step-by-step explanation:
31 km is the right answer
