Answer:
25 min, 48 sec
Explanation:
Alan:
t = d/v
= 400 mi / 46 mph = 8.70 hr
So it took Alan 8.70 hrs; from 8 am, that's 4:42 pm that he arrives.
t = d/v
= 400 mi / 55 mph = 7.27 hr
So it took Beth 7.27 hrs; from 9 am, that's 4:16:12 that she arrives.
4:42 - 4:16:12 = 25.8 minutes = 25 minutes, 48 sec

Answer:
Only B is correct.
Explanation:
Electrolysis and galvanic activity are two different ways of the passage of electricity. Electrolysis occurs at a spontaneous reaction, and galvanic activity needs an external force to happen.
For example, a cell works by a redox reaction, in which a material reduces (gain electrons), and the other oxides (loses electrons). As higher is the standard reduction potential of a material, as easy is to it to reduces. Thus, if a cell works with the reduction happens with the material with low standard reduction potential, then it works by galvanic activity.
When electronics are connected to the house system, it's necessary to do the ground connection, which will allow the electrons that are dissipated to go to the earth. So, it is done incorrectly, the electrons flow to the equipment, which they natural path. So, the electrolysis can occur with a poor ground connection.
