Distance covered by an hour hand in 12hours=(2×22/7×42/10)cm
264/10=26.4cm
Distance covered by an hour hand in a day=(2×26.4)cm=52.8cm
Distance covered by minute hand in 1 hour=(2×22/7×7)
=44cm
Distance covered by minute hand in 1 day=(44×24)cm=1056cm
Now,sum of the distance covered by their tips in a day=(52.8+1056)cm
=1108.8cm
264/10=26.4cm
Distance covered by an hour hand in a day=(2×26.4)cm=52.8cm
Distance covered by minute hand in 1 hour=(2×22/7×7)
