A cyclist starts from his home at point O. He rides 6.0 km due east in 20 min and then 8.0 km due north in 40 min, maintaining uniform speed on each segment.
(i) Find the total distance covered.
(ii) Determine the total time taken.
(iii) Calculate the magnitude and direction of the displacement from O to the final position.
(iv) Compute the average speed for the journey.
(v) Obtain the magnitude and direction of the average velocity.
