Question

4. A person travelling on a straight line moves with a
uniform velocity vi for some time and with uniform
velocity v, for the next equal time. The average velocity
v is given by​

Answer 1

Answer:

well, let's in both cases he travelled for time t

then, total distance covered by him =(vit+vt)

total time taken = 2t

then average velocity =

$\frac{total \: distane}{total \: time}$

=

$\frac{vit + vt}{2t}$

=

$\frac{vi + v}{2}$
