...Not sure how to attack this:
Find, correct to 3 decimal places, the anle in radians through which:
a) the second hand of a clock turns in 7 seconds
b) the hour hand of a clock turns between 6am and 6.40am
in one hour, the hour hand moves 1/12 of a revolution.
40 min = 2/3 hr
how much of a revolution will the hour hand turn in 40 min? ... remember there are 2pi radians in a revolution
