Question 1 · Maths
A train travels 270 km in 3 hours. What is its average speed in km/h?
Answer: 90 km/h. Speed = distance ÷ time = 270 ÷ 3 = 90 km/h.
Question 2 · Maths
What is 35% of 240?
Answer: 84. 10% of 240 = 24. So 30% = 72 and 5% = 12. 35% = 72 + 12 = 84.
Question 3 · English / Vocabulary
Which word is most similar in meaning to BENEVOLENT?
Answer: kind. Benevolent means well-meaning and kind towards others.

Answer: 162. Each term is multiplied by 3: 2×3=6, 6×3=18, 18×3=54, 54×3=162.
Question 6 · Maths
A bag contains 3 red, 5 blue and 2 green marbles. One marble is picked at random. What is the probability it is blue?

Question 9 · Maths
A rectangle has a perimeter of 56 cm. Its length is 18 cm. What is its width?
