Given Information:
- Deepak walks 20 meters towards the North.
- He then turns left and walks 40 meters.
- He again turns left and walks 20 meters.
- He moves 20 meters after turning to the right.
Analysis:To determine Deepak's final position, we need to consider the directions and distances he has walked.
Step 1: Moving towards the NorthDeepak walks 20 meters towards the North. This means he moves straight ahead without any change in direction.
Step 2: Turning Left and Walking 40 metersAfter moving North, Deepak turns left and walks 40 meters. This means he changes his direction to the West and covers a distance of 40 meters.
Step 3: Turning Left and Walking 20 metersNext, Deepak turns left again and walks 20 meters. This means he changes his direction to the South and covers a distance of 20 meters.
Step 4: Turning Right and Walking 20 metersFinally, Deepak turns to the right and walks 20 meters. This means he changes his direction to the West and covers a distance of 20 meters.
Calculating the Final Position:To calculate the final position, we need to consider the net displacement in the North-South and East-West directions.
North-South Displacement:Deepak initially moves 20 meters towards the North and then 20 meters towards the South. Therefore, the net displacement in the North-South direction is 20 - 20 = 0 meters.
East-West Displacement:Deepak initially moves 40 meters towards the West and then 20 meters towards the West. Therefore, the net displacement in the East-West direction is 40 + 20 = 60 meters towards the West.
Final Position:Since the net displacement in the North-South direction is 0 meters and the net displacement in the East-West direction is 60 meters towards the West, Deepak is 60 meters away from his original position in the West direction.
Therefore, the correct answer is option B) 60 meters.
