Question

length and breadth of a playground are 80m and 40m respectively. How long will a boy take to complete 6 rounds of the ground if he walks at the rate of 2 m/ s?

Answer 1

as it depend on the perimeter, may be 720 sec..

Answer 2

Heya

Here goes the answer.

Length of the playground=80m

Breadth of the playground=40m

Perimeter = 2(length+breadth)

=2(80+40)

= 2(120)

= 240m

One round is 240m

6 rounds = 6×240 = 1440

Speed = Distance/Time

Time = Distance/speed

= 1440/2

= 720sec

= 12min
