Question

the area of a square field is60025 m a man cycles along its boundry at 118km/hr in how much time will he return at the starting point​

Answer 1

Answer

Given,

The area of square field : 60025 sq. km.

The speed of cyclist : 118 km/ hr

Or

The speed of cyclist : 32.778 m/sec

TO FIND ,

The time taken by the cyclist to complete one round around the square field.

We know that area of square = side × side

So, 60025 = $\rm (side)^2$

Side = 245m

Length of boundry of square = perimeter of square = 4 × side

4 × 245 = 980m

Hence boundry = 980 m

We know that,

Speed = $\rm \frac { Distance } { time }$

Time = $\rm \frac { 980 } { 32.778 }$

Time taken will be : 29.898 seconds

i.e approx 30 second when estimated
