In a homogeneous mixture, the ingredients are distributed evenly throughout the mixture, while in a heterogeneous mixture, the ingredients are unevenly distributed.
The sailboat is about 0.83m/sec (rounded to the nearest tenth).
To find speed, you would calculate distance over time.
100 meters/120 seconds = 0.83 meters per second
You would end up with a brown/black color depending on how much of each pigment was added! Hope this helps.
