Joseph jogs from one end A to the other end B of a straight 300 m road in 2 minutes 50 seconds and then turns around and jogs 100 m back to point C in another 1 minute. What are Joseph�s average speeds and velocities in jogging
(a) from A to B and
(b) from A to C?
Distance covered = 300 m
Displacement = 300 m
Time taken = 2 min 50 sec = (2 x 60) + 50 = 170 sec
From point A to C,
Distance covered = (300 +100)m = 400 m
Displacement = (300 - 100)m = 200 m
Time taken = 3 min 50 sec = (3 x 60) + 50 = 230 sec
