Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

The total distance covered = Area of semi-circle. As, diameter of semi-circle = 4 So, radius of semi-circle = diameter/2 = 4/2 = 2 Area of semi-circle = π×r×r/2 = π×2×2/2 = 2π Hence, total distance covered is 2π m.
time only has value I.e 4 s
We have to consider semi-circle.
