If two resistors with resistances R1 and R2 are connected in parallel, as in the figure, then

Question:

If two resistors with resistances R1 and R2 are connected in parallel, as in the figure, then the total resistance R, measured in ohms (Ω), is given by 1/R = 1/R1 + 1/R2 If R1 and R2 are increasing at rates of 0.3Ω/s and 0.2Ω/s, respectively, how fast is R changing when R1 = 80Ω and R2 = 100 Ω?
