Answer 1

Answer:

10.56 minutes

Step-by-step explanation:

Given, radius (r) = 35 m.

(i)

Given,Speed = 5 km/hr

(ii)

Circumference of the field = 2πr

                                            = 2 * (22/7) * 35

                                            = 220 m

                                            = 0.22 km.

Given that he go four times around a circumference.

So, Distance covered = 4 * 0.22

                                    = 0.88 km

We know that Time = Total distance/Speed

                                 = 0.88/5

                                 = 0.176 hr

                                 = 0.176 * 60

                                 = 10.56 min.

Therefore, The total time taken = 10.56 minutes.
