Question 99524: the area of aquare field is 60025 m. square. A man cycles along its boundary at 18 km/hr. I how much time will he return at the starting point. Answer by edjones(8007) (Show Source):
You can put this solution on YOUR website! t=time s=speed d=distance m =.245 km (1 side of the field)
perimeter = 4*.245=.980 km
t=d/s
t=.980/18=49/900 hr
49/900*60=49/15 min= 3 min 16 sec
