Step-by-step explanation:
An example of direct variation would be the relationship of distance with time when speed is constant.
Let's assume you travel at the speed of 60 mph. The distance at 0, 0.5, 1, 2 hours would be 0, 30, 60, 120 miles.
This is a linear relationship and produces a graph of line.
See the graph.
--------------------
An example of inverse variation would be the time to complete the same work as number of workers increase.
- t = w/p, where w is work (constant), p- number of workers
Assume 5 workers complete wok in 20 days, 10 workers do same in 10 days, 20 workers do in 5 days.
This relationship produces a curved line.
See the graph.
