Question

Area of square field is 60025m2 A man moves long it boundary at 18 Km\hr In how much time will he return to starting point

Answer 1

Area =60025 m square

let the length be x

x^2=60025

So x= 245 m

Perimeter=4*x= 980 m

Speed =18 km/h =18*5/18 m/s =5 m/s

Time= distance/speed

=980/5

=196 s

So he will return to the starting point in 196 s
