Two pumping wells 1000 m away fully penetrate the same confined aquifer. One of the wells pumps at a rate of 1240 m3/d. The second well pumps at 850 m3/d. If the aquifer has a transmissivity of 2000 m2/d and a storage coefficient of 4x10-4, when would the wells start interfering with each other

Assume you measured the mass of the cart to be (500 ± 1) g and the mass of the additional mass you put on the cart to be (500 ± 1) g as well. since the scale you are using in the lab cannot measure objects heavier than 600g you will have to sum up individual pieces and propagate the error. so what would be the mass and the standard error of the cart and the mass
