Is this car worth fixing or should I just get rid of it

What is your question?

Well at first I could smell coolant while driving cause was leaking into my hot motor then it started pretty much spraying it from what looked like underneath the water pump and now coolant is pouring out under the front of my car and behind the driverside rear tire area and when I stop all you see is smoke coming from my back tire and what sounds like hissing

How long has your 2010 Mercury Mountaineer had this problem?

Few weeks now
