  1. A helicopter travels 240 miles in 2 hours. What is its average speed in miles per hour?

    Answer: 120 mph

    Speed = Distance / Time = 240 / 2 = 120 mph.

  2. If fuel costs $4.50 per gallon and a helicopter uses 35 gallons per hour, how much does a 3-hour flight cost in fuel?

    Answer: $472.50

    Fuel per flight = 35 gal/hr × 3 hr = 105 gallons. Cost = 105 × $4.50 = $472.50.

  3. Solve for x: 3x + 7 = 22

    Answer: x = 5

    Subtract 7 from both sides: 3x = 15. Divide by 3: x = 5.

  4. A circle has a radius of 7 cm. What is its area? (Use π ≈ 3.14)

    Answer: 153.86 cm²

    Area = πr² = 3.14 × 7² = 3.14 × 49 = 153.86 cm².

  5. A unit has 240 soldiers. If 15% are assigned to aviation duties, how many soldiers work in aviation?

    Answer: 36

    15% of 240 = 0.15 × 240 = 36 soldiers.

  6. What is the value of 2³ × 4²?

    Answer: 128

    2³ = 8; 4² = 16; 8 × 16 = 128.
