Question

The area of square field is 900msquare how much time will a girl take to run 10 times around it at rate of 6km/hr

Answer 1

İf area is 900m², the side must be √900=30m

Perimeter of square= 120m (30×4)

=0.120km

Speed=6km/h

Distance to be covered= (10×0.120)km= 1.2 km

Thus,

Time= distance/speed

=(6/1.2)h=5h
