Answer:
By calculating the time taken to reach we get to know that the The time taken by the other person is less than yourself
Step-by-step explanation:
Given that the other person and yourself left at the same time and the speed of the other person is 60 miles per hour and the speed of yourself is 40 miles per hour.
We know that the 
Let the time taken to reach the destination at a distance of d by the other person is T1.
Then 

Let the time taken to reach the destination at a distance of d by the yourself is T2.
Then 

Now the time difference is = T2-T1 =
= 
Therefore T1 > T2 which means the time taken to reach the destination by yourself is greater than that of other person .
A whole box would be 1/4 so half of 1/4 is 1/8.
Answer: Choice A) An economic theory that is shared by the discipline of Psychology
Through the research I've found so far, the articles mention that economic choices have a psychological link. This is because economics is basically the study of human psychology (more or less) in terms of how to allocate resources and how best to use them. The law of diminishing marginal utility is basically the idea where the concept "more is always better" is simply not true. An example would be that you are at a restaurant and there's an endless buffet. The food isn't infinite and neither is the capacity of your stomach. After a certain point, you'll find that eating another burger isn't as satisfying as eating the first few burgers. You can think of it as a graph where the curve may start with a sharp increase, but eventually it levels off.
Side note: The term "affective habituation" may be used in psychology textbooks as something very similar to the law of diminishing marginal utility.
Fractions and percents are simply.different ways to express a ratio between two numbers.
