Question

Your class starts at 12:12PM and ended at 12:50PM what angle did the minute hand of watch sweep through during the class

Answer 1

we know that

12:50PM-12:12PM=38 minutes

30 minutes in the minute hand of watch is equal an angle of 180 degrees

so

by proportion

30/180=38/x-------> 30*x=180*38--------> x=180*38/30------> x=228°

therefore

the answer is

228 degrees
