Answer:

The answer to the question is;

The distance the tip of the minute and travels as time progresses from 12:00 to 12:25 is 18.33 in.

Explanation:

To solve the question, we note that

Number of minutes in one complete revolution of the clock = 60

Position travel of the minute hand = 12:00 to 12:25 = 25 minutes

Fraction of complete revolution traveled by minute hand = 25/60

Distance of one complete revolution = Circumference of circle = 2·π·r

Length of minute hand = 7 inches = r

Distance of one complete revolution = 2 × π × 7 = 43.98 in

Distance traveled by minute hand = 25/60×43.98 in = 18.33 in.
