How much time will a horse take to run around a square field of side 175 m if it runs at the speed of 15 km/hr?
Answer & explanation
Correct answer: option 4
15 km/h= 15 × \(\frac{5 }{18}\) km/h = \(\frac{25 }{6}\) km/h
Perimeter of square = 4 × 175 = 700 m
Time = \(\frac{6 }{25 }\) × 700
= 168 sec
