1 minute walk (1/60)*360 degrees =6 hours walk (1/60) * (360/12) =1/2 degrees.
Let uncle go out at 6: 00 and go home at 6: 00.
It is known that the hour hand and the minute hand are 120 degrees.
1. 180+( 1/2)x-6x = 120
Where 180+( 1/2) x is the angle between the hour hand and 12, and 6x is the angle between the minute hand and 12.
The solution is that x = 120/ 1 1 is about 1 1 minute, that is, go out around 6 o'clock, 1 1.
2.6y- 180-( 1/2)y = 120
As mentioned above, y=600/ 1 1 is about 54 minutes, that is, going home around 6: 54: 30.
The time of committing the crime is somewhere in between.
