The Answer is 20.
1: First, add up all the temperatures that has been provided, 21 + 21 + 19 + 19. It should give you 80.
2: Divide 80 by how many temperatures has been shown. There were 4 temperatures shown, so 80/4 = 20. Hope this helps you!
The formula for displacement is:
<span>d=1/2(v0+v)t
If we multiply by 2/t we will have
2*d/t = v0+v
In order to find v0 we subtract </span><span>v (the final velocity)
2*d/t - v = v0
The final result is that: v0 = </span>2*d/t - v
