The minute hand of this clock is 10.5 cm long. How far does its tip travel from the time on clock A to the time on clock B? (Take \π= 227.)

Question

Accepted Answer

49.5 cm. A shows 3:05 and B shows 3:50: 45 minutes, i.e. 34 of a turn. Distance = 34×2× 227×10.5=49.5 cm. (66 cm is a full turn; 33 cm is half.)
