Absolutism is a form of government where all power is in the hands of a single ruler. In addition to being a tyrannical and dictatorial government, it exercises all 3 powers in one. The 3 powers are: executive, legislative and judiciary. In absolutism these powers are in the hands of the monarch, if he wants to create a law out of nothing, he goes there and does it. But this government doesn't work anymore (in fact it never did), it concentrates power in a single place and at one point it doesn't work anymore, because problems appear, like the one that led to the French Revolution. This government left the population with a great economic crisis, this caused revolts to happen and this government to fall.
Answer:
A.46.7mph
B.50mph
Explanation:
We know that from the data given
Julie drove 50 miles at a speed of 38 mph, and another 50 miles for 62mph. Thus , for the first 50 miles, she drove for the following time
T1= distance/speed
====> 50/38= 1.3hrs
the next 50 miles, she drove for
T2= 50/62
= 0.8hrs
So average speed is
Totaldistance/ total time
100/2.1
= 46.7mph
B. Because the time she used driving at 35 mph is the same amount of time she used driving at 65 mph, the average speed is just the average of the two speeds given which is
(50+50)/2 = 50mph
