    Clock Problem

    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

    and

    b) the hour hand of a clock turns between 6am and 6.40am

    Cheers

    \textcolor{red}{\frac{7}{60} \cdot 2\pi}

    and

    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


    Cheers
