A skating champion moves along the circumference of a circle of radius 28 m in 44 sec. How many seconds will it take her to move along the perimeter of a hexagon of side 48 m ?

Answer: Option C

Distance mode by the skater in 44 sec
= Circumference of the circle
= $$\left(2\times \frac{22}{7}\times 28\right)$$     m
= 176 m
Speed of skater :
= $$\left(\frac{176}{44}\right)$$   m/sec
= 4 m/sec
Perimeter of hexagon :
= (6 × 48) m
= 288 m
∴ Required difference :
= $$\left(\frac{288}{4}\right)$$   sec
= 72 sec
