Question for Practice Questions Level 2: Direction Sense
Try yourself:Rocky drives a car in the east direction and covers 100 km. Then he takes a turn and moves 80 km in the north direction. After that, he takes a left turn and covers 40 km, and reaches his destination. How much distance is he away from the starting position?
Explanation
Distance OD = OA – CB
= 100 km – 40 km
= 60 km
By Pythagoras theorem,
OC2 = CD2 + DO2
= (6400 + 3600) km2
= 10000 km2
Taking square root both sides, we get
OC = 100 km

Try yourself:I start from my home and go 2 km straight. Then, I turn towards my right and go 1 km. I turn again towards my right and go 1 km. If now I am north-west from my home, then in which direction did I start in the beginning?
Explanation
Clearly, the route is as shown in figure A.
It is given that the person is finally to the north-west of his house. Rotating figure A 90° anticlockwise, we obtain figure B satisfying the specified conditions.
It is evident from the figure that the direction of walking in the beginning was west.
