Sneha jogs along a straight road from her home to the school gate, which is 2.5 km due east of her home. She reaches the gate in 18 min. Immediately she realises that she has dropped a notebook and runs 1.25 km back toward her home in 6 min. She then turns again and covers the remaining 1.25 km to the school in 9 min.
(a) Find the total distance travelled and the displacement of Sneha at the end of her journey.
(b) Calculate the total time taken.
(c) Compute Sneha’s average speed for the complete trip.
(d) Compute the magnitude and direction of her average velocity.
