The answer in mixed number is $=4\frac{0}{2}$

Step-by-step explanation:

Note: When a body is travelling at uniform acceleration, the average velocity is given as $Average -velocity= \frac{v+u}{2}\\\\$

Given

initial velocity u= 3 m/s

final velocity v= 5 m/s

$Average -velocity= \frac{5+3}{2}\\\\$

$Average-velocity= \frac{8}{2}$

To express this in mixed number we have $=4\frac{0}{2}$

Step-by-step explanation:

18+12=30

30X4=120

120/2=60

You need to add the bottom and the top of the trapezoid, times the height, and divided them by two.
