The perimeter application problem of the sixth grade mathematical circle
Judging from the meaning of the question, the length of the minute hand is 60 mm, and the length of the hour hand is 60 ÷ 6× 5 = 50 mm.

The circumference of clockwise rotation is: 50×2×3. 14=3 14 mm.

The hour hand turns once, and the minute hand turns 12 turn;

The circumference of 12 is: 60× 2× 3.14×12 = 4521.6 mm.

The needle tip of the hour hand goes 3 14 mm, and the needle tip of the minute hand goes 4521.6 mm.
