hey mate your answers is
I'm trying to workout this problem, but I am still struggling to understand the logic to solve this problem.
hour degree = 360 / 12 = 30 minutes degree = 360 / 12 / 60 = 0.5
So, according to this, I thought I could formulate the following function in python:
def clockangles(hour, min): return (hour * 30) + (min * 0.5)
For the hour, it works fine, as it appears to have a 1=1 mapping. But for the minute there is one problem at least. When it's 0 minutes, the minutes hand points to 12.
For example:
7pm: hands pointing to 7pm and minutes pointing to 12
How do I calculate the minutes properly? Please help me understand the formula.
EDIT: For example, if I call the function above with 7pm, e.g clockangles(7,0) I get the value 210. However, according this link the angle at 7:00 is 150
hope its help you
