how many degrees does the minute hand move each hour
To make the hour hand move from one number to the next which is 30 degrees, the minute hand moves 360 degrees. Therefore you know that the minute hand moves 18 degrees when 3 minutes has past. So cross multiply! \[30=360\] \[x=3\] Find x by cross multiplying. \[x=\frac{3\times 30}{360}\]
