Area of square playground = a²
a² = 256.6404
a = √256.64
a = 16 m ( approx.)
so,
the perimeter of playground = 4a
perimeter = 4×16
perimeter = 64m²
it means that , the men covers 64m² distance at the speed of 6km/ hr.
→ time taken by the men to cover 64m² = ???
→ speed in m/s = 6× 5 ÷ 18
→ speed = 1.6 m/s
→ speed = distance ÷ time
→ 1.6 = 64 ÷ t
→ t = 64 × 1.6
→ t = 102.4 sec.
TIME TAKEN FOR FIVE REVOLUTION.. = t × 5
→ 102.4 × 5
→ 512 sec...
