An object moves along a distance MN. The first half of the block moves with a speed v1 = 30km/h. The second half of the way the object moves in two stages: in the first half, the object travels with a speed v2 = 20km/h, the second half goes at a speed v3 = 10km/h. Calculate the average speed of the object over the whole distance MN.
