Answer»

o, lets assume Hari was getting fat and being self conscious he started running early in the morning. He decided to run uniformly ALONG a square path of side 100m. A.T.Q.Hari ran 3 ROUNDS AROUND this park.So, the distance travelled =3×100= 300 mNow, he ran those 300 metres in a span of 4 minutes, i.e., 4×60= 240seconds.since, we KNOW,Speed (s) = Distance (d) ÷ Time (t)In this CASE,Distance = 300mTime = 240 sso, Speed of Hari= (300÷240)= 1.25 m/sso, the speed of Hari is 1.25 m/s
