Inverse variation is the relationship that occurs between two quantities in which one decreases as the other increases.
Inverse variation
The types of variation which exists are;
- Inverse variation
- Direct variation
- Joint variation
For instance;
The relationship between John's speed and distance is inversely proportional. If John's speed is 5km/h, his distance is 6km. Find John's distance when his speed increases to 6km/h.
s = k / d
where,
k = constant of proportionality
s = k / d
5 = k/6
30 = k
s = k / d
6 = 30/d
6d = 30
d = 30/6
d = 5 km
