Question : Directions: A goes 7 km eastward, then turns right and proceeds 7 km. Then travels 15 km towards left, then travels 12 km towards left, and finally goes 5 km northward. Calculate his distance from his initial place in the horizontal direction.
Option 1: 20 km
Option 2: 22 km
Option 3: 23 km
Option 4: 25 km
Correct Answer: 22 km
Solution :
In the above figure, O is the starting point and T is the finishing point.
A's distance from his initial place in the horizontal direction is (OP + QR).
OP + QR = 7 + 15 = 22 km
So, A is 22 km from the starting point in the horizontal direction. Hence, the second option is correct.
