Question

the area of the square field is 60025 m sq. . A man cycles along it's boundary at 18km/h. In how much time will he return to the starting point?

Answer 1

Answer:

side of square field = √area

side = 245

so perimeter = 245*4 = 980

speed = 18km/h

speed = 18 * 5/18 ( for conversion from km/h to m/s)

speed = 5 m/s

so time taken by the cyclist = 980/5 = 196sec

so the time taken is 3 minutes 3 seconds
