Physics in grade one of senior high school: description of speed of motion -- speed The average velocity of an object passing through two consecutive equal displacements is V1 and V2 respectively, and the average velocity in the whole process is v = 12m / s. given V1 = 10m / s, the size of V2 can be calculated Give the operation process, thank you!

Let the total displacement be x0, x0 / 2 = X1 = x2
x1/v1+x2/v2=x0/v
If we omit all x, we have to:
1/20+1/2v2=1/12
The solution is: V2 = 15m / s
