Question

.The area of a rectangular field is 3584msq. and its length is 64m.A boy runs around the field at the rate of 8km/h.How much time will he take to go 5times around it.

Answer 1

Answer:

Step-by-step explanation:

Breadth of the field = Area/length = 3584/64 = 56m

Perimeter of the field = 2*(64+56) = 240m

The boy covers five rounds of the field so the total distance covered by the boy = 240*5 = 1200m or 1.2km

Now time = distance/speed = 1.2/6 = 0.2 hrs = 12min

So the boy will go five times around the field in 12 min.
