Step by step explanation please ​

Step-by-step explanation:

In 2 days, the short hand will complete 4 rounds.

∴ Distance moved by its tip 4(circumference of a circle of radius 4 cm)

=> 4×(2×22/7×4) cm

In 2 days, the long hand will complete 48 rounds.

∴ Distance moved by its tip 48(circumference of a circle of radius 6 cm)

=> 48×(2×22/7×6)cm = 12.672cm

Hence,

sum of distances moved by the tips of two hands of the clock

=> (704/7+12672)cm = 1910.85cm
