Download Solution PDFGiven:
Side of the square field = 38 metres.
Speed of the boy = 6 km/h.
Formula Used:
Time taken to complete one round = Distance / Speed
Calculation:
Distance covered in one round = Perimeter of the square field
Perimeter = 4 × Side = 4 × 38 = 152 metres
Speed of the boy in m/s = Speed in km/h × (1000 / 3600)
Speed = 6 × (1000 / 3600) = 5/3 m/s
Time taken = Distance / Speed
⇒ Time taken = 152 / (5/3) = 152 × (3/5)
⇒ Time taken = 456 / 5 = 91.2 seconds
The boy will take 91.2 seconds to complete one round around the square field.
