Question

The area of rectangle field is 3584 m and it's length is 64m . A boys runs around the field at the rate of 6km|h . How long will he take to go 5 times around it

Answer 1

Step-by-step explanation:

let l & b be the length & breadth of the rectangle.

l*b = 3584

l =64 m

hence b =3584/64 = 56 m

perimeter = (64+56)*2 = 240 m

speed of boys = 5/3 m/s

time = distance/speed

= (5*240)/(5/3) = 720 sec = 12 mins
