What is an example of inversely proportional?

Answer 1

If quantity A is directly proportional to another quantity B, it means that if B is doubled so is A. When B is tripled so is A. It also works in the other direction; if A is tripled so is B. It works for any factor.

In mathematical terms one may write:

A = C * B

Where C is some numerical constant.

Answer 2

If Y is one variable and X the other then if Y = kX they are directly proportional (k is a constant). If X increases, Y increases. On the other hand if Y = k / X they are inversely proportional (k is a constant). If X increases, Y decreases..

Answer 3

The time it takes you to get to grandma's house in the next city

is inversely proportional to the speed at which you drive there.

double your speed ---> 1/2 the time

triple your speed ---> 1/3 the time

half the speed ---> double the time

Answer 4

It is a relationship between two variables, x and y which is defined by xy = c where c is some constant.

In such a relationship, an increase in x leads to a decrease in y and conversely.

Answer 5

An example of an inversely proportional relationship is the relationship between the time it takes to travel a certain distance and the speed at which you are traveling. As speed increases, the time it takes to travel the distance decreases.

Answer 6

As one value increases, the other decreases; so, if you double one number you have to halve the other number

Answer 7

Two variables are said to be directly proportional if an increase or decrease in one variable causes simultaneous increase or decrease in another variable.

Answer 8

For example the number 5. * A direct proportion would be 5/1 * The inverse would be 1/5

Answer 9

There is no way that you can tell if two numbers are in any sort of proportional relationship. You need a minimum of two sets of ordered pairs.
