Problem
A cyclist rides westward on a straight country road with an average speed of 18kmh−1. The ride lasts exactly 40min.
(i) Calculate the distance covered.
(ii) Taking the westward direction as negative, determine the displacement of the cyclist from the starting point.
(iii) Using the sign convention of part (ii), find the average velocity of the cyclist, stating both its magnitude and direction.
