With the wind a jet takes 3 hours to fly 1890 miles. Against the wind, it takes 4 hours for the same trip. Find the winds speed and the planes speed. (Let p=planes speed and w=winds speed.)

A: 3(p+w)=1890
4(p-w)=1890

B: 3(w+p)=1890
4(w-p)=1890

C: 3(p-w)=1890
4(p+w)=1890

D: 1890(p+w)=3
1890(p-w)=4
