Q:

# What is inverse variation?

A:

Inverse variation is defined as the relationship between two variables in which the resultant product is a constant. If a is inversely proportional to b, the form of equation is a = k/b, where k is a constant.

Inverse variation is known as the opposite of direct variation. If there is an increase in one variable, the other variable decreases in proportion so that the resultant product remains unchanged. For example, a car travelling at 10 mph can cover 10 miles in an hour. If the speed of the car decreases to 5 mph, the number of hours it would take to cover the 10-mile distance increases to two hours.
