What are some linear equations from real life?

Real-life examples of linear equations include distance and rate problems, pricing problems, calculating dimensions and mixing different percentages of solutions. One application of linear equations is illustrated in finding the time it takes for two cars moving toward each other at different speeds to reach the same point. read more

One example of a linear equation from real life is the equation which represents the physical phenomenon of air resistance in otherwise free fall. The equation -cv(t) = ma(t) is a linear equation. read more

In real life, the two variables of the equations are husband and wife in a family. The relationship between the two variables gives a straight line in linear equations. Likewise, both husband and wife in the family must shed their differences and should go in the same direction to run the family smoothly. read more
