How much time will a horse take to run around a square field of side 750 m if it runs at the speed of 25 km/h ?
Answer & explanation
Correct answer: option 2
Distance = Speed × Time
To convert km/h into m/sec .
X km/h × \(\frac{5}{18}\) = Y m/sec
25 km/h × \(\frac{5}{18}\) = 25 × \(\frac{5}{18}\) m/sec
750 = 25 × \(\frac{5}{18}\) × T
T = 18 × 6 = 108
Time for all 4 sides = 108 × 4 = 432 sec.
