 * __<span style="font-family: 'Comic Sans MS',cursive; font-size: 150%;">Functions __** <span style="font-family: 'Comic Sans MS',cursive; font-size: 150%;">In our physical experience we often come across quantities which, are not related in any way. There is no relationship between the height of a student and their percentage mark in a test. However, there are other quantities where the value of one depends upon or is determined by the value of the other. For example, if a car is travelling at a constant speed of 60 km/h then the distance travelled is determined by the time elapsed. If the time is given, then the distance can be calculated.
