To take out the distance covered in 1 hour,we will take out the circumference.
C=2πr
=2*3.14*15
=3.14*30
=94.2cm
C=2πr
=2*3.14*15
=3.14*30
=94.2cm

In this case the length of minute hand would work as radius and one revolution made by it would be the distance covered by its tip in 1 hour and 1 revolution is the circumference.
So,
Circumference=2πr
=2×3.14×15cm
=94.2cm
So,
Circumference=2πr
=2×3.14×15cm
=94.2cm
