Easy -1.8 This is a straightforward unit conversion question requiring only the knowledge that 1 revolution = 2π radians, 1 minute = 60 seconds, and basic arithmetic (72 ÷ 60 × 2π). It's a 1-mark multiple choice question with no problem-solving element, making it significantly easier than average A-level questions.
