Question

The area of a square field is 60025 m^2 a man cycles along its boundary at the speed of 18 km per hr in how much time will he return

Answer 1

Area of square = 60025 m^2 = (a)^2 is the formula so we get side = 245 m

Speed = 18 kmph = 18* (5/18) mps = 5 mps

Distance = 245 * 4 = 980 m

Time = D/S = 980/5 = 196 seconds
