ANSWER :

An hour hand completes 2 rotations in 1 day i.e, in 24 hours.

Therefore, distance covered by the hour hand in 1 day = 2×circumference=2×2πr

=2×2×

7

×4.2 cm

=52.8 cm

Minute hand completes 24 rotations in 1 day.

Therefore, distance covered by the minute hand in 1 day

=24×circumference

=24×2×

7

×7=1056 cm

Therefore,

Sum of the distance covered by the tips of two hands =52.8+1056=1108.8 cm
