A rectangle field is measured 290m dy 210m. How long it will take for a girl to go two times round the feild, if she walk at the rate of 1.5 m/sec?
The length of the field = 290 Mtrs.
Width of the field = 210 Mtrs.
If the girl has to go around the field, then we have to find out the perimeter of the rectangular field;
Primeter of the rectangular field = 2(L + B) = 2 ( 290 + 210) = 2 x 500 = 1000 Mtrs.
Since the girl goes around the field twice, the the distance covered by her will be = 2 x 1000 = 2000 Mtrs.
The time taken by the girl to go around the field = Distance/ Speed = 2000/1.5 = 1333.33 secs = 1333.33/60 mins = 22.22 mins.
Ans: 22.22 Mins.
