Question

A boy goes from A to B with a velocity of 20 m/min and comes back from B 1 point
to A with a velocity of 30 m/min. The average velocity of the boy during the
whole journey is


tell fast very important will mark you as the branniest

Answer 1

Answer:

0

Explanation:

zero

Average velocity =

Total time

Total displacement

Since, in this case, the particle initial and final points are the same, therefore its Displacement =0.

∴Average velocity=0

Answer 2

Answer:

24m/min

Explanation:

2xy/x+y... Average velocity..
