Take the number of degrees in a circle (360º)-the sun moves around earth in a circular fashion, which is how I got the 360º to approximate. Then divide it by the number of hours in a day (24 hours). 
This comes to 15 degrees per hour. However, the angle changes 15º -> 55º for this problem, which means you have a 40º difference. $$\frac{ 40º }{ 15º } = ?? $$
