Ответ:
The solution is made up of the solvent and solute.
The solvent and solute are separated by physical means.
Explanation:
Any mixture must have a solvent and solute, or else it can't be classified as a mixture.
Additionally, I took a test and debated between the "distillation" and "physical means" problem, and got the "distillation" one wrong. It does make sense; evaporation is a physical mean through which the solvent is separates from the solute, even if it isn't caused by humans.
The 4th one just sounds absurd, and I would be shocked if it were correct.
Ответ:
I believe that the answer is B. Scott had the faster speed since he rode at 20 k/h while Jill only traveled 10 km/h. Because Jill had only gone 5 kilometers vs Scott going a full 10 kileters double what Jill had went.
Have a nice day!
