Answer
$150^o$
Work Step by Step
There are 12 hours around a clock.
One rotation around the clock makes 360 degrees.
This means that in each hour, a clock's hand moves:
$=\dfrac{360^o}{12}
\\=30^o$
There are 5 hours from 12 o'clock to 5 o'clock.
This means that from 12 to 5 o'clock, the clock's hour hand moves:
$=5(30^o)
\\=150^o$
