Variation can be direct, inverse or joint
The constant of variation is one-eighth
How to determine the constant of variation
The variation is given as:
[tex]m \to pr[/tex] --- the joint variation
Rewrite as an equation
[tex]m = kpr[/tex]
Where k represents the constant of variation
When p is 2 and r is 4, m is 1.
So, we have:
[tex]1 = k * 2 * 4[/tex]
This gives
[tex]1 = 8k[/tex]
Solve for k
[tex]k = \frac 18[/tex]
Hence, the constant of variation is one-eighth
