Question : Directions: A plane flies 100 km west, then turns south and flies 150 km, then turns west and flies 300 km, then turns to its right and flies 150 km. Where is it now with reference to its starting position?
Option 1: 400 km east
Option 2: 200 km west
Option 3: 400 km west
Option 4: 200 km east
Correct Answer: 400 km west
Solution :
Firstly, we will draw the diagram as per the given instructions –
Now, we have to find the distance from the starting point to the endpoint –
The distance from the starting point to the endpoint = 300 + 100 = 400 km
Therefore, the plane is in the west direction with respect to its starting point, and the distance between its starting point and final point is 400 km. Hence, the third option is correct.
