  1. If a train travels 240 miles in 4 hours, what is its average speed in miles per hour?

    Answer: 60 mph

    Average speed equals total distance divided by total time: 240 ÷ 4 = 60 mph.

  2. What is the value of x if 3x + 7 = 22?

    Answer: 5

    Subtract 7 from both sides to get 3x = 15, then divide by 3 to get x = 5.

  3. A rectangle has a length of 12 cm and a width of 8 cm. What is its area?

    Answer: 96 cm²

    The area of a rectangle is length × width: 12 × 8 = 96 cm².

  4. What is 15% of 200?

    Answer: 30

    15% of 200 = 0.15 × 200 = 30.

  5. If the ratio of boys to girls in a class is 3:4 and there are 28 students total, how many boys are there?

    Answer: 12

    Boys = (3/7) × 28 = 12, since the total ratio parts are 3 + 4 = 7.

  6. What is the least common multiple (LCM) of 6 and 9?
