1.2: 30 to 2: 55, walking for 25 minutes is 5/ 12 hours. 25 minutes is 5/ 12 of a circle, then the minute hand turns 360*5/ 12= 150 degrees; 5/ 12 hour is 5/288 of a circle, so the clockwise rotation is 360*5/288=6.25 degrees.

2.2: 15, the upper hand and 12 are 360*2.25/ 12=67.5 degrees, and the upper hand and 12 are 360*25/60= 150 degrees.
