If two resistors of R₁ and R₂ ohms are connected in parallel in an electric circuit to make an R-ohm resistor, the value of R can be found from the equation

If R₁ is decreasing at the rate of 1 ohm / sec and R₂ is increasing at the rate of 0.5 ohm / sec, at what rate is R changing when R₁ = 75 ohms and R₂ = 50 ohms?
