half the distance with speed of 3 m/s. The
other half of the distane is covered in two
equal time intervals with speed of 4.5 m/s
and 7.5 m/s respectively. The average
speed of the particle during this motion is
(a) 4.0 m/s (b)5.0 m/s
(c) 5.5m/s​

Answer 1

Answer:

Average Speed = [7.5+4.5+3]/3

= 5.0 m/s

I hope this helps.
