please answer my question . only quality answers needed

Answer 1

if the body goes A to B with vel. 4 and B to C with vel. of 6 and 2 for equal time
now, formula for average vel-equal time
v1 + v2/2
so 2 + 6/2= 4
so now vel. A to B is 4 and vel. B to C is 4
formula for average vel. equal dist.
2v1v2/v1+v2
so average vel thruoghput the journey is
2 × 4 × 4/4 + 4 = 32/8 = 4
so average velocity is 4 m/s
