. Calculate the distance between the planes after 6 hours. Give your answer in km, to the nearest km. km
Answer: 2392 kilometers.
Explanation:
To find the distance between the two aircraft after 6 hours, we can use the Pythagorean theorem because they are moving at right angles to each other (one due south and the other due east). Here's how to calculate it:
First, calculate the distance traveled by each aircraft in 6 hours.
1. Aircraft traveling south:
Distance = Velocity × Time
Distance = 85 m/s × (6 hours × 3600 seconds/hour)
Distance = 85 m/s × 21600 s
Distance = 1836000 meters
2. Aircraft traveling east:
Distance = Velocity × Time
Distance = 71 m/s × (6 hours × 3600 seconds/hour)
Distance = 71 m/s × 21600 s
Distance = 1533600 meters
Now, we have the two sides of a right triangle:
- The southbound distance is 1836000 meters.
- The eastbound distance is 1533600 meters.
We can use the Pythagorean theorem to find the hypotenuse (distance between the aircraft):
Distance = √(southbound distance² + eastbound distance²)
Distance = √((1836000 m)² + (1533600 m)²)
Distance ≈ √(3376416000000 m² + 2352089600000 m²)
Distance ≈ √(5728505600000 m²)
Distance ≈ 2391760.78 meters
Now, let's convert the distance to kilometers:
Distance ≈ 2391.76 kilometers
Rounding to the nearest kilometer, the distance between the two aircraft after 6 hours is approximately 2392 kilometers.
