The famous clock tower in London has a minute hand that is 14 feet long. How far does the tip of the minute hand of Big Ben travel in 35 minutes?

Think of the clock's face as a circle. You've been given the length of the minute hand: that tells you the radius of the circle. Use that to work out its circumference (I'm sure you already know the formula for that), then - as 35 minutes is seven-twelfths of 60 minutes - work out what seven-twelfths of that circumference is.
