S=4hr make r the subject of the formula
To make r the subject of the formula, we need to isolate r on one side of the equation.
Given that S = 4hr, we can rearrange the equation as follows:
S = r * t (where t is the time)
Since we know t = 4hr, we can substitute this value in the equation:
S = r * 4hr
To make r the subject, we need to divide both sides of the equation by 4hr:
S /(4hr) = (r * 4hr) /(4hr)
Simplifying, we get:
S/(4hr) = r * (4hr/4hr)
S/(4hr) = r
Therefore, the formula for making r the subject is r = S/(4hr).
