In 10 minutes a person can walk around a rectangular field of 300 m X 200 m. The speed (in kmph) of the person is

Solution

Perimeter of the rectangular = 2(300+200) = 2 x 500 = 1000 m

Distance walked in 10 mins = 1000 m

Hence, Distance walked in 60 mins = 1000 x 6 = 6000 m = 6km

$$\therefore\ $$Speed of the person = 6kmph
