Question

Hari is jogging uniformly along a square path of side 100m. He makes 3 rounds along this square path in 4 minutes, his speed is ?

Answer 1

Heya!!

So, 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 m

Now, 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 = 300m
Time = 240 s

so, Speed of Hari= (300÷240)= 1.25 m/s

so, the speed of Hari is 1.25 m/s
