Example
Joe and Sara are driving in the same direction. Joe’s velocity is 90 km/h and Sara’s 100 km/h. If we take Joe’s velocity as and Sara’s then
This is the velocity observed by Joe. Joe sees Sara moving at 10 km/h.
Joe and Sara are driving in the opposite directions i.e heading towards each other or moving away from each other. Joe’s velocity is 90 km/h and Sara’s 100 km/h. If we take Joe’s velocity as and Sara’s then
This is the velocity observed by Joe. Joe sees Sara moving at 190 km/h.

Famous quotes containing the word example:
“Our intellect is not the most subtle, the most powerful, the most appropriate, instrument for revealing the truth. It is life that, little by little, example by example, permits us to see that what is most important to our heart, or to our mind, is learned not by reasoning but through other agencies. Then it is that the intellect, observing their superiority, abdicates its control to them upon reasoned grounds and agrees to become their collaborator and lackey.”
—Marcel Proust (1871–1922)
