Explanation Consider the speed of train is measured in kilometer per hour because two cities are always very far from each other like 300 km apart and taken to cover this distance is in hours so, the speed of train is measured in Km per hour. Whereas the movement of an insect is measured in very short interval of time so the distance covered in this time interval is very small like in mm. The speed of an insect is meaured in mm per hour. 1 Kilometer = 1000000 millimeter 1 hour = 3600 seconds That gives, 1 Km per hour = 1000000

Equations and Inequations

Equations and inequalities describe the relationship between two mathematical expressions.

Linear Functions

A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
