If s=1/2make t the subject of the formula

There does not seem to be any given formula relating s and t. Please provide more information.

To make t the subject of the formula when s = 1/2, we need to isolate t on one side of the equation.

Given that s = 1/2, we can rearrange the formula as follows:

s = t/2

To find t, we can multiply both sides of the equation by 2:

2s = t

Therefore, the subject of the formula when s = 1/2 is t = 2s.
