Question

2. 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?​

Answer 1

Answer:

a) 1.739 m/sec b) 0.869m/sec

Explanation:

a) Average speed = total distance / total time

= 300+100/2×60 +50+60

= 400/230

= 1.739m/sec

b) Average Velocity = total displacement/total time

= 300-100/230

=200/230

= 0.869m/sec
