Question

Joseph jogs from one end A to other end B of a straight 300m road in 2 minutes 30 seconds and then turns around and jogs 100m 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 ? ​

Answer 1

Answer:

Av velocity(A to B) = total displacement / total time

= 300/2*60+30

=300/150

=2m/s

av velocity (A to C) =300-100/210=200/210
