Free Air Traffic Controller: Math Question and Answers ā Questions and Answers
Question 1: In 90 minutes, an aircraft has traveled 375 miles. What is the ground speed of the aircraft?
- 200 kts
- 150 kts
- 300 kts
- 250 kts (Correct answer)
Correct answer: 250 kts
To calculate ground speed, divide the distance traveled by the time taken. The aircraft traveled 375 miles in 90 minutes, which is equivalent to 1.5 hours. Therefore, 375 miles / 1.5 hours = 250 miles per hour (knots).
Question 2: If an aircraft flies at 450 MPH for 2<sup>1</sup>ā<sub>2</sub> hours, how many miles has it covered?
- 1075
- 1125 (Correct answer)
- 1050
- 1100
Correct answer: 1125
To find the total distance covered, multiply the speed by the time. The aircraft flies at 450 MPH for 2.5 hours. So, 450 MPH multiplied by 2.5 hours equals 1125 miles.
Question 3: How many miles would a plane travel in 1 hour and 45 minutes at a speed of 200 mph with a 15 mph tailwind?
- 300
- 315
- 360
- 376.25 (Correct answer)
Correct answer: 376.25
First, calculate the effective speed by adding the tailwind to the aircraft's speed: 200 mph + 15 mph = 215 mph. Next, convert the flight time to hours: 1 hour and 45 minutes is 1.75 hours. Finally, multiply the effective speed by the time: 215 mph * 1.75 hours = 376.25 miles.
Question 4: How many miles will a plane travel if it flies at 220 mph for four hours?
- 800
- 820
- 850
- 880 (Correct answer)
Correct answer: 880
To calculate the total distance, multiply the speed by the time. The plane flies at 220 mph for 4 hours. Therefore, 220 mph multiplied by 4 hours equals 880 miles.
Question 5: Milwaukee is 350 miles away from Minneapolis. In order to complete this flight in less than three hours, what speed must N2540G maintain?
- 110
- 115
- 120
- 116.67 (Correct answer)
Correct answer: 116.67
To find the required speed, divide the distance by the time. The distance is 350 miles, and the goal is to complete the flight in less than three hours. Therefore, the speed must be greater than 350 miles / 3 hours, which is approximately 116.67 mph. Among the given options, 116.67 mph represents the minimum average speed needed to achieve this goal.
Question 6: What is the average speed in MPH for a 9-hour flight covering 1800 miles?
- 150
- 200 (Correct answer)
- 250
- 280
Correct answer: 200
To calculate the average speed, divide the total distance by the total time. The flight covers 1800 miles in 9 hours. Therefore, 1800 miles divided by 9 hours equals 200 miles per hour (MPH).
Question 7: How many miles apart are New York City and Cleveland if it takes N74985 (280 MPH) one hour and thirty minutes to fly between them?
- 280
- 300
- 420 (Correct answer)
- 500
Correct answer: 420
To find the distance, multiply the speed by the time. The plane flies at 280 MPH for one hour and thirty minutes, which is equivalent to 1.5 hours. So, 280 MPH multiplied by 1.5 hours equals 420 miles.
