The tip of the hour hand travels round a circle of radius 4 in, covering a complete revolution in 12 hours. You know the formula for the circumference of the circle. So what fraction of that will be be covered in 1hr 20 min?if the hour hand of a clock has a length of 4 in. how far does its tip travel in 1hr and 20min?
No. 4/3 divided by 12 is $\dfrac4{3\times12}$.4/3/12 = 16 is this right?
No, we want:4/3/12 = 16 is this right?
