To determine how far Samir is from the police station, we need to analyze the given information step by step.
Step 1: Initial movement
Samir starts from the police station and travels straight for a distance of 4 km. This means that he moves in a straight line without making any turns. So, after this movement, he is 4 km away from the police station.
Step 2: First left turn
After traveling straight for 4 km, Samir turns left for the market. He then travels straight for 600 meters. This means that he moves 600 meters in a direction perpendicular to his initial movement.
To visualize this, we can consider a right-angled triangle where the hypotenuse represents Samir's initial movement of 4 km, and the perpendicular side represents his movement towards the market. The other side of the triangle represents Samir's distance from the police station after the first left turn.
Using the Pythagorean theorem, we can calculate the length of the other side of the triangle:
(4 km)^2 = (distance from police station)^2 + (600 meters)^2
Simplifying the equation:
16 km^2 - 0.36 km^2 = (distance from police station)^2
15.64 km^2 = (distance from police station)^2
Taking the square root of both sides:
distance from police station = √15.64 km^2
distance from police station = 3.95 km (approximately)
Step 3: Second left turn
After traveling straight for 600 meters towards the market, Samir makes another left turn. He then travels straight for 200 meters. This means that he moves 200 meters in a direction perpendicular to his previous movement.
To calculate the new distance from the police station, we can again use the Pythagorean theorem:
(3.95 km)^2 = (new distance from police station)^2 + (200 meters)^2
15.6 km^2 - 0.04 km^2 = (new distance from police station)^2
15.56 km^2 = (new distance from police station)^2
Taking the square root of both sides:
new distance from police station = √15.56 km^2
new distance from police station = 3.95 km (approximately)
Step 4: Third left turn
After traveling straight for 200 meters, Samir makes another left turn. He then travels straight for 600 meters. This means that he moves 600 meters in a direction perpendicular to his previous movement.
Again, we can use the Pythagorean theorem to calculate the final distance from the police station:
(3.95 km)^2 = (final distance from police station)^2 + (600 meters)^2
15.6 km^2 - 0.36 km^2 = (final distance from police station)^2
15.24 km^2 = (final distance from police station)^2
Taking the square root of both sides:
final distance from police station = √15.24 km^2
final distance from police station = 3.91 km (approximately)
Therefore, Samir is approximately 3.91 km away from the police station.
The correct answer is option B: 3.8 km.
Step 1: Initial movement
Samir starts from the police station and travels straight for a distance of 4 km. This means that he moves in a straight line without making any turns. So, after this movement, he is 4 km away from the police station.
Step 2: First left turn
After traveling straight for 4 km, Samir turns left for the market. He then travels straight for 600 meters. This means that he moves 600 meters in a direction perpendicular to his initial movement.
To visualize this, we can consider a right-angled triangle where the hypotenuse represents Samir's initial movement of 4 km, and the perpendicular side represents his movement towards the market. The other side of the triangle represents Samir's distance from the police station after the first left turn.
Using the Pythagorean theorem, we can calculate the length of the other side of the triangle:
(4 km)^2 = (distance from police station)^2 + (600 meters)^2
Simplifying the equation:
16 km^2 - 0.36 km^2 = (distance from police station)^2
15.64 km^2 = (distance from police station)^2
Taking the square root of both sides:
distance from police station = √15.64 km^2
distance from police station = 3.95 km (approximately)
Step 3: Second left turn
After traveling straight for 600 meters towards the market, Samir makes another left turn. He then travels straight for 200 meters. This means that he moves 200 meters in a direction perpendicular to his previous movement.
To calculate the new distance from the police station, we can again use the Pythagorean theorem:
(3.95 km)^2 = (new distance from police station)^2 + (200 meters)^2
15.6 km^2 - 0.04 km^2 = (new distance from police station)^2
15.56 km^2 = (new distance from police station)^2
Taking the square root of both sides:
new distance from police station = √15.56 km^2
new distance from police station = 3.95 km (approximately)
Step 4: Third left turn
After traveling straight for 200 meters, Samir makes another left turn. He then travels straight for 600 meters. This means that he moves 600 meters in a direction perpendicular to his previous movement.
Again, we can use the Pythagorean theorem to calculate the final distance from the police station:
(3.95 km)^2 = (final distance from police station)^2 + (600 meters)^2
15.6 km^2 - 0.36 km^2 = (final distance from police station)^2
15.24 km^2 = (final distance from police station)^2
Taking the square root of both sides:
final distance from police station = √15.24 km^2
final distance from police station = 3.91 km (approximately)
Therefore, Samir is approximately 3.91 km away from the police station.
The correct answer is option B: 3.8 km.
