Interpreting graphical information

After studying this section, you will be able to:

• use and interpret graphs involving practical situations

Graphs of real-life situations

NOTE: A very common error made is to assume that a distance−time graph shows a ‘picture’ of the hill because of its slope. Nothing could be further from the truth − the steeper the hill, all things being equal, the less steep the line on the distance−time graph (slower speed)!
